4,4′-oxydianiline and its salts (CAS 101-80-4) — Safety Data Sheet
IARC Group 2B — Possibly carcinogenic to humans
CAS: 101-80-4 | IARC source
Safety data sheet documentation for 4,4′-oxydianiline and its salts (CAS 101-80-4), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H350, H340, H361f, H331). 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: 8 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.

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.

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.

The Hansen parameters fall outside the range of the method, so the distance Ra cannot be calculated, and the database holds no solubility measurement to put in its place. Rather than eleven ratings with nothing behind them, we show none. Base the solvent choice on the safety data sheet and on experimental data.

⚠️ 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.

Why this page can be checked
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.
Import documentation for CAS 101-80-4 (4,4′-oxydianiline and its salts), compiled from the binding classification rather than from a supplier’s summary. The product is the document.
4,4′-oxydianiline and its salts (CAS 101-80-4) at a glance
Substance – 4,4′-oxydianiline and its salts
CAS number – 101-80-4
EC number – 202-977-0
CLP Annex VI index number – 612-199-00-7
Also known as – p-aminophenyl ether
Hazard statements – H350 (may cause cancer); H340 (may cause genetic defects); H361f; H331 (toxic if inhaled); H311 (toxic in contact with skin); H301 (toxic if swallowed)
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.
How do I check if my SDS for 4,4′-oxydianiline and its salts is still valid?
If a sheet for 4,4′-oxydianiline and its salts is already in circulation, the useful first question is not whether to replace it but whether it is wrong, and if so in which section. Defects repeat across a catalogue, so three documents usually reveal what three hundred need.
Aquatic hazard and disposal
Aquatic hazard classification (H411) for CAS 101-80-4 reaches beyond the label. It governs the environmental section of the safety data sheet, the disposal route stated in section 13, and in several Member States the reporting threshold for storage. Consignments carrying an aquatic hazard also attract marine pollutant marking when moved by sea.
Storage and handling in the document
The store manager responsible for managing material with CAS number 101-80-4 must review Section 7 first to determine its compatibility with adjacent materials, required atmosphere conditions, and any segregation rules arising from its classification. The necessary information regarding these aspects must be explicitly stated in the documentation provided, rather than relying on supplier email correspondence.
Which GHS pictograms apply to 4,4′-oxydianiline and its salts?
The label for 4,4′-oxydianiline and its salts carries GHS06 (skull and crossbones), GHS08 (health hazard), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 101-80-4, 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.
Why a correct sheet stops being correct
Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 101-80-4 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.
First-aid content and why it is read first
Section 4 details first-aid measures for 4,4′-oxydianiline and its salts according to exposure routes: inhalation, skin contact, eye exposure, and ingestion, providing specific guidance for each scenario. The primary shortcoming is the generic advice to ‘seek medical attention’ across all four situations; this recommendation is most pertinent when immediate assistance is required.
Stability, reactivity and incompatibilities
Section 10 records stability and reactivity for 4,4′-oxydianiline and its salts: conditions to avoid, incompatible materials, and hazardous decomposition products. This is the section a laboratory consults before placing two substances on the same shelf.
What is the EC number for 4,4′-oxydianiline and its salts?
Alongside CAS 101-80-4, this substance carries EC number 202-977-0 and Annex VI index 612-199-00-7. 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.
What must the label for 4,4′-oxydianiline and its salts contain?
The supply label for 4,4′-oxydianiline and its salts 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, H340, H361f… 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.
Where is regulatory status recorded for 4,4′-oxydianiline and its salts?
The regulatory status of 4,4′-oxydianiline and its salts evolves separately from its hazard classification. A substance may maintain consistent hazard characteristics over extended periods while gaining additional obligations under Section 15, leading to this section becoming outdated more rapidly than Section 2.
How is 4,4′-oxydianiline and its salts classified for road, sea and air transport?
Transport classification for 4,4′-oxydianiline and its salts sits in section 14 and differs by mode: ADR for road, IMDG for sea, IATA for air. A sheet that prints all three without stating which applies leaves the shipper to choose, and the shipper is the one penalised for choosing wrong.
Identifiers that must agree
Three identifiers accompany this substance, and all must align: the CAS number 101-80-4, the Annex VI index number 612-199-00-7, and the name as listed in the register. Incongruent identifiers represent the subtlest flaw in a documentation set, as each individual document appears correct until a cross-check reveals they describe distinct entities.
What is the CLP classification of 4,4′-oxydianiline and its salts?
The harmonised classification for CAS 101-80-4 carries 7 hazard statements: H350, H340, H361f, H331, H311, H301, H411. In plain terms this means may cause cancer; may cause genetic defects; H361f; toxic if inhaled. 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 4,4′-oxydianiline and its salts classified as a CMR substance?
CAS 101-80-4 is classified as a CMR substance (H350, H340). 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.
What happens if a consignment of 4,4′-oxydianiline and its salts is refused?
Refusals concerning 4,4′-oxydianiline and its salts usually stem from three primary reasons: outdated classification resulting from amendments, discrepancies between transport data and shipping documents, and language barriers when the receiving authority does not accept the submitted documentation. These issues are not evident to a reader who views the document as professionally prepared.
Questions about documentation for 4,4′-oxydianiline and its salts
What hazard statements apply to CAS 101-80-4?
The harmonised entry lists H350, H340, H361f, H331. These are binding across the Union and may not be softened by a self-classification.
In which language must the sheet be supplied?
In an official language of each Member State where 4,4′-oxydianiline and its salts is placed on the market, unless that State has stated otherwise.
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 4,4′-oxydianiline and its salts 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.

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.
