α-chlorotoluene (CAS 100-44-7) — Safety Data Sheet
Safety data sheet documentation for α-chlorotoluene (CAS 100-44-7), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H350, H331, H302, H335). Two options: a working draft sent by e-mail immediately, or a signed card issued within 72 hours of complete input. The item supplied is a document — MolGod.org does not sell, supply or ship chemical substances.
Free, and generated automatically from the sources listed on this page. No person has reviewed it, and it describes the substance in general — not your material, your process or your intended market.
Section 9 — physicochemical properties: 10 of 22 established.
We show what is established and name what is not. Classification and identity are complete on every card; section 9 is where public data is thin.
Identity, structure, physical and chemical properties, analytical data and the literature — every value with the source it came from and the date that source was read. The full record is in the data sections further down this page.
Identity CAS · EC · IUPAC · synonyms · molecular formula · molecular weight
Structure 2D · 3D · SMILES · InChI · InChIKey
Physical melting point · boiling point · density · vapour pressure · solubility
Chemical reactivity · stability · incompatible materials
Analytical spectra and methods where available
References literature, with DOI where a DOI exists
Identifier coverage is shown as a count, not as a quality rating. It tells you how well characterised this substance is in public data — which is a different question from how good it is, and a more useful one when you are deciding whether the documentation behind it can be defended.
This page sells the documentation for this substance, not the substance. Choose the level you need.
€0Audit the sheet you already haveSend us your existing sheet for this substance and we tell you what is wrong with it. One per company. If it turns out to be sound, you buy nothing.Start the free audit →
€49.99Working draftThe complete sixteen-section document, referenced, downloadable immediately after checkout. The right choice while the paperwork is still moving.
€249.99Signed cardThe same document reviewed and signed, issued within 72 hours of complete input — for the moment somebody official asks who stands behind it.
Documentation available for this substance: safety data sheet · CLP label · certificate of analysis on request · specification. Languages: the official language of your destination market, produced per card.
Grade, purity, physical form, packaging, minimum order and lead time are not shown, because MolGod does not supply the material — those are facts about a seller, and there is no seller on this page. They appear on storefronts we build for suppliers, where somebody can answer for them.
What a compliance officer checks, and where it sits in the document. The values themselves are in the regulatory sections further down.
Classification harmonised entry with index number where one exists; self-classification shown separately and labelled, never merged
Hazard statements the official text, in the page language
Precautionary statements combined statements reproduced whole, never split
Pictograms and signal word
Inventory status per jurisdiction, each stated individually
Restrictions entry and scope where one applies
Authorisation entry and sunset date where one applies
Candidate list status and the supply-chain duty it triggers
Transport entry per mode — road, sea, air
Exposure limits per country, each naming the act it comes from
Document status revision date and the amendment in force when issued
Fields with no established status say so. This page never states that no restrictions apply — absence from a dataset is not clearance, and a document that treats it as clearance is the most dangerous kind of document in this field.
A digital PDF safety data sheet in the sixteen-section structure of REACH Annex II (Regulation 1907/2006).
Substance identification, hazard classification, physicochemical, toxicological and ecological information, and regulatory references.
Classification read against the harmonised entry in CLP Annex VI where one exists for the substance.
A version number, a compilation date, and the source behind each value that carries one.
Delivery by e-mail. Nothing is shipped.
What this is not
Not a chemical substance, not a sample, not any physical goods.
Not a certification. No official certification scheme for safety data sheets exists in the European Union.
Not legal approval, and not a guarantee of compliance in any jurisdiction.
Not a substitute for your own regulatory assessment, nor for the safety data sheet supplied by the manufacturer or importer of the substance you actually hold.
Not adapted to a specific workplace, process or national annex unless you provide that information.
Where the available evidence does not support a value, the sheet states that the value is not established rather than estimating one. A field with no recorded source is marked as such.
What is in the buyer pack
Everything your compliance officer will ask for, in one file.
The product page as PDF — the record as published, so what you forward matches what you read.
The safety data sheet at your entitlement level — sixteen sections in the order set by REACH Annex II, for this substance, in the language you select.
The CLP label artwork — generated from the same classification as the sheet, so the two cannot disagree.
The specification, and the certificate of analysis where batch data exists.
sources.txt — every citation with the date it was read.
An explicit list of what we could not establish — fields marked unavailable rather than filled with an estimate. This is the honest part of the document and we do not hide it in a footnote.
Your European buyer is going to forward this to somebody who was not on the call. The pack exists so that what they forward is complete, self-explanatory and traceable — rather than four attachments and a sentence beginning “I think this is everything”.
These switch the language of this page. Single substances. Mixtures on enquiry. One document, one language — additional languages are priced separately. Every version, including the Chinese one, is written to EU law — (EC) No 1907/2006 (REACH) Annex II and (EU) 2020/878 — and translated from it. The Chinese version is a reference translation, not a legally valid document for the Chinese market: an SDS for China must be compiled separately to GB/T 16483 and GB/T 17519.

🎓 Gids voor spectruminterpretatie (voor studenten)
An explanation of every band in the spectrum — why it appears where it does, and what it shows about the structure.
IR (infrarood) (6 pieken)
Widmo IR (infrarood) zawiera 6 zidentyfikowanych strukturalnie pasm (z 10 wykrytych łącznie: 4 poza rozpoznawanymi zakresami). Poniższa analiza tłumaczy, co każde z nich znaczy strukturalnie i dlaczego pojawia się w danym zakresie.
C–H stretch (=C–H, aromatic)CH_arom● high
Band "C–H stretch (=C–H, aromatic)" verschijnt in de gevallen: 3,042.0 cm⁻¹ (zwak (w)), 3,082.0 cm⁻¹ (zwak (w)). Aromatische (sp²) C–H — altijd boven 3000 cm⁻¹, in tegenstelling tot alkyl-C–H.
C–H bend (CH3, CH2 — methyl/methylene)CH3/CH2● high
Band "C–H bend (CH3, CH2 — methyl/methylene)" verschijnt in de gevallen: 1,450.0 cm⁻¹ (zwak (w)). Dit is de rekvibratie van alifatische sp³ C–H-bindingen. Aanwezig in vrijwel elke organische verbinding met een alkylketen.
C–H out-of-plane bend (aromatic substitution pattern)aromatic_sub● medium
Band "C–H out-of-plane bend (aromatic substitution pattern)" verschijnt in de gevallen: 698.0 cm⁻¹ (sterk (s)), 762.0 cm⁻¹ (zwak (w)), 810.0 cm⁻¹ (zwak (w)). De functionele groep wordt geïdentificeerd op basis van het karakteristieke bereik (Pavia/Silverstein) — het precieze fysische mechanisme hangt af van de dichtstbijzijnde chemische buren.

🌐 Hansen Solubility Sphere (3D)
⚠️ The Hansen parameters for this substance fall outside the range of the method.
At least one of the δD/δP/δH parameters fell outside the domain of validity of the group contribution method (Hoftyzer–Van Krevelen), so the position of the molecule in Hansen space is unknown. The distance Ra is measured FROM THAT POINT — it cannot be calculated without knowing the point. The sphere and the distance table have been omitted rather than filled with numbers that have nothing behind them. Where a solubility measurement exists, it is shown in the table below.
CAS, EC and molecular formula, resolved across the identifier systems a buyer uses. The count of systems resolved is shown, so you can see how well characterised this substance is rather than assuming.
Data
Every physicochemical value carries the source it came from and the date that source was read. Open any of them.
Classification
Read against the harmonised entry where one exists, with the index number stated. Self-classification is shown separately and labelled.
Regulatory
Inventory, restriction, authorisation and candidate-list status, each stated individually. Where a status is not established, this page says so — it never says no restrictions apply.
Documentation
Which documents exist, at what review level, in which languages, and when each was issued.
Supplier
Who is selling this, and what they have published about themselves.
Nothing on this page is a certification. It is a record you can audit.
Two guarantees, both with their limits stated
The Gap Report Guarantee
If the available evidence cannot support a defensible document for your CAS number and product specification, we will not invent the missing values. You receive a documented gap report and choose: a refund, store credit, or the report on its own.
A visible gap is worth more than a plausible number, because the plausible number is the one that fails when somebody checks it.
The Re-issue Promise
If a signed card is rejected by an authority or by a customer’s compliance officer on one of the points we checked and reported as passed, we re-issue it corrected at no charge and credit the original fee.
This covers the checks we performed and named. It does not cover registration status, tonnage, or your role in the supply chain — those are not ours to hold, and a guarantee that pretended otherwise would be worth nothing.
This page describes the regulatory documentation issued for α-chlorotoluene (CAS 100-44-7). The item supplied is a document, not the substance.
α-chlorotoluene (CAS 100-44-7) at a glance
Substance – α-chlorotoluene
CAS number – 100-44-7
EC number – 202-853-6
CLP Annex VI index number – 602-037-00-3
Also known as – benzyl chloride
Hazard statements – H350 (may cause cancer); H331 (toxic if inhaled); H302 (harmful if swallowed); H335 (may cause respiratory irritation); H373 (may cause damage to organs through prolonged or repeated exposure); H315 (causes skin irritation)
CMR classification – yes, classified as carcinogenic, mutagenic or toxic for reproduction
Documentation issued – safety data sheet in REACH Annex II structure; working draft or signed card
What is supplied – a document. MolGod.org does not sell, supply or ship chemical substances.
What must the label for α-chlorotoluene contain?
The supply label for α-chlorotoluene is generated from the same classification that drives the safety data sheet: pictograms selected by precedence, one signal word derived from the highest hazard class present, and the hazard statements H350, H331, H302… reproduced in full. Where the container is too small to carry the complete set at a legible size, there are lawful ways to handle it and unlawful ones that look identical to a non-specialist.
Why a correct sheet stops being correct
Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 100-44-7 written before the amendment that touched its entry keeps stating a classification the register no longer holds. Nothing in the document announces this — it reads exactly as it did on the day it was issued, which is precisely why revision dates are checked before content.
Where is regulatory status recorded for α-chlorotoluene?
Section 15 documents the regulatory status for α-chlorotoluene, detailing its inclusion on candidate lists, whether it is subject to authorisation or restriction, along with any applicable national regulations. This information is frequently requested by downstream users; providing a concise summary in a single document eliminates repetitive email exchanges with each customer.
In which language must the SDS for α-chlorotoluene be supplied?
The documentation for α-chlorotoluene is limited by its original language. Translation in this context is not an editorial task; hazard statements must use their official wording in each language, as any rephrasing — even if accurate — would result in a document that no longer aligns with the required format. The phrasing is strictly defined and must be reproduced exactly, rather than being interpreted or adapted.
Disposal route and waste classification
Disposal of α-chlorotoluene and its packaging must comply with section 13 requirements. The substance is classified as posing an aquatic hazard, meaning it cannot be discharged into drains. The waste code assigned by the holder should reflect the hazard profile rather than convenience, ensuring proper management in accordance with regulatory guidelines.
Can I import α-chlorotoluene into the EU?
The introduction of α-chlorotoluene into the Union necessitates the preparation of documentation prior to logistical arrangements. The documentation file must be available at the time of import, not merely upon request; for this purpose, substances listed in CLP Annex VI is assessed within the context of regulated consignments. Index 602-037-00-3 establishes the classification that Section 2 must reflect accordingly.
What is the CLP classification of α-chlorotoluene?
The harmonised classification for CAS 100-44-7 carries 7 hazard statements: H350, H331, H302, H335, H373, H315, H318. In plain terms this means may cause cancer; toxic if inhaled; harmful if swallowed; may cause respiratory irritation. A harmonised entry is binding across the Union — an importer may not soften it, and a self-classification that diverges from it will not survive an enforcement check.
Is α-chlorotoluene classified as a CMR substance?
CAS 100-44-7 is classified as a CMR substance (H350). That status changes the obligations attached to every shipment: workplace exposure documentation, restrictions on supply to the general public, and substitution pressure from downstream users who must justify continued use. A safety data sheet for a CMR substance is read more closely than any other, because the classification itself invites scrutiny.
Which GHS pictograms apply to α-chlorotoluene?
The label for α-chlorotoluene carries GHS05 (corrosion), GHS06 (skull and crossbones), GHS08 (health hazard), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 100-44-7, and the precedence rules in Annex I decide which pictogram is dropped when two would say the same thing. A label showing a different set from the register is wrong even if every hazard statement on it is correct.
First-aid content and why it is read first
Section 4 covers first-aid measures for α-chlorotoluene by route of exposure: inhalation, skin, eye and ingestion, each answered separately. Generic advice to ‘seek medical attention’ in all four is the most common defect, and it is the one that matters at the moment somebody needs the sheet.
What do customs check when importing α-chlorotoluene?
When a consignment of α-chlorotoluene is stopped at the border, the document examined first is rarely the invoice. It is section 14 of the safety data sheet and its agreement with the transport papers. A missing packing group, an absent UN number or a proper shipping name that contradicts the classification of CAS 100-44-7 will hold the pallet regardless of how complete the remaining fifteen sections are.
Stability, reactivity and incompatibilities
Incompatibilities for α-chlorotoluene should be detailed under section 10 and must not conflict with the storage instructions provided in section 7. If a document lists a material as incompatible in one section while permitting its use in another, it is no longer considered valid.
How is α-chlorotoluene classified for road, sea and air transport?
Carriers and forwarders handling α-chlorotoluene compare section 14 against the shipping papers before loading. Any disagreement stops the consignment at the point where correcting it is most expensive.
Identifiers that must agree
The CAS 100-44-7 number and index number 602-037-00-3 are not interchangeable or decorative elements; they serve distinct purposes. The index number connects to the harmonised classification system, whereas the CAS number links to chemical literature. A document containing one without the other requires readers to independently reconstruct this relationship, which may lead to errors during reconstruction.
What is the EC number for α-chlorotoluene?
Alongside CAS 100-44-7, this substance carries EC number 202-853-6 and Annex VI index 602-037-00-3. European documentation is built around the EC number as often as around the CAS: registration dossiers, the candidate list and customs systems key on it. A safety data sheet quoting only one of the two forces every downstream reader to look up the other.
Questions about documentation for α-chlorotoluene
Can I check whether my existing sheet is still valid?
Yes. A section-by-section reading against Annex II and the current harmonised entry establishes that in one pass, and a sheet that passes is reported as passing.
Do I need a safety data sheet to import α-chlorotoluene into the EU?
Yes. A sheet compiled to Annex II of REACH must exist before the first consignment moves, and it must be held by the entity placing the substance on the Union market.
What is the CAS number of α-chlorotoluene?
CAS 100-44-7. In CLP Annex VI the same substance carries index number 602-037-00-3, and both identifiers should appear in the documentation.
Is α-chlorotoluene a CMR substance?
Yes. The harmonised classification places it among substances classified as carcinogenic, mutagenic or toxic for reproduction, which changes workplace documentation and supply restrictions.

Nothing stops you sending a draft to anyone. "Not written for this" means exactly that: it carries no signature and no fields adapted to your company, so it will not answer the questions the recipient is about to ask.
What the signature means
Who prepares the document
The document is generated by the MolGod engine from ECHA CLP Annex VI and the cited public sources, then read section by section by a qualified scientific reviewer with a degree in chemistry or a related scientific field.
What the review covers
The sheet is read section by section against the REACH Annex II structure. GHS classification and transport entries are checked against the sources cited in the document, and the sheet is adapted to the company, product grade and identified use you provide.
What is NOT verified
We do not test your material and we cannot confirm what is physically in your container: composition, concentration, impurities or manufacturing route. Those come from you and are reproduced as supplied.
What the signature is — and is not
The signature records that a qualified scientific reviewer read the document. It is not a government approval, not an ECHA approval, and not a legal certification — no such certification exists for safety data sheets in the EU. A signature does not by itself make a document legally valid or make your business compliant.
What you receive
A PDF in the 16-section REACH Annex II structure, signed and dated, with version information and a list of anything we could not establish. Five rounds of corrections are included.
Delivery
Within 72 hours of receiving complete input from you. The clock pauses whenever we are waiting on an answer.
Refunds
Full refund before review begins. If the evidence is insufficient, you choose a refund, store credit or a gap report. See the refund policy.
No fabricated-data guarantee.
If the available evidence is insufficient to support a defensible document for this CAS number and your product specification, we will not invent the missing values. You may choose a refund, store credit or a documented gap report.
The supplier placing the substance or mixture on the market remains responsible for ensuring that the final safety data sheet matches the material, its identified uses and their legal role in the supply chain.
