Safety data sheet documentation for vanillin (CAS 121-33-5), compiled to REACH Annex II. Vanillin has no harmonised entry in CLP Annex VI; the sheet states its classification basis (aggregated ECHA C&L notifications). 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.

€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.

About the downloads (Type of data: Type of data not reported by the source (may be measured or calculated)) JCAMP: the NMRShiftDB file as received (JCAMP-DX 5.01 text). It is a peak list: chemical shift in ppm. MolGod adds header lines stating the type of data; the values are unchanged. CSV: the same peak list in two columns. The second column repeats the shift value; it is not a signal intensity. Lines starting with # state the type of data. PNG: a picture of the plot above, with the type of data written on it. Use: where signals are expected or were reported (chemical shift positions). Not included or guaranteed: intensities, multiplicities, coupling constants, line shapes, and solvent or temperature unless stated. A predicted list is not a measurement and cannot serve as a reference spectrum for identity or purity testing. Downloads become active after Show.
De gegevens worden eenmalig opgehaald (JCAMP-DX-parser) en opgeslagen in de lokale database van de plug-in. Geen dubbele downloads, geen NIST-verzoeken bij volgende keren openen. Licenties worden gerespecteerd (alleen een deeplink en een eigen visualisatie worden gepubliceerd).
Gegevens worden live opgehaald uit meerdere bronnen (priority-chain). JCAMP-DX / CSV / PNG beschikbaar om te downloaden onder elk spectrum.

🌐 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.

Identity
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.
For vanillin (CAS 121-33-5) the documentation obligation begins before the first shipment. This page sets out what the safety data sheet has to establish.
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 is the CLP classification of vanillin?
Vanillin has no harmonised entry in CLP Annex VI, so there is no binding classification to copy. The sheet carries the classification derived from aggregated notifications in the ECHA C&L Inventory and states that basis in section 2; the importer remains responsible for confirming it against the manufacturer’s data.
Disposal route and waste classification
Disposal of vanillin and of its packaging is section 13, and it has to align with the classification: a substance with an aquatic hazard cannot be routed to drain, and the waste code assigned by the holder follows from the hazard profile, not from convenience.
How is vanillin classified for road, sea and air transport?
Section 14 for CAS 121-33-5 carries the UN number, proper shipping name, class, packing group and environmental hazard where these apply. Where the substance is not dangerous for carriage, the section says so explicitly rather than being left empty — an empty section 14 reads as an omission, not as an absence of hazard.

When you get it
Immediately after payment
Within 72 hours of complete input
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.
