4,4′-oxydianiline and its salts (CAS 101-80-4) — Safety Data Sheet

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.

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.

Purity, certificates and what the sheet does not say

Purity grade is a certificate question, not a safety data sheet question. The sheet for 4,4′-oxydianiline and its salts describes the substance; a certificate of analysis describes one batch of it, with the measured result against the specification and the analytical method named per parameter. Laboratories asking for ‘the COA’ usually need both documents.

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.

Who is responsible for REACH compliance for 4,4′-oxydianiline and its salts?

The obligation attached to 4,4′-oxydianiline and its salts follows the act of importing, not the act of manufacturing. A distributor buying inside the Union inherits a lighter duty than one who imports directly, and confusing the two is expensive: the importer must hold the full file, while the distributor may rely on what was passed down.

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-[CAS?], 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.

In which language must the SDS for 4,4′-oxydianiline and its salts be supplied?

A safety data sheet must be supplied in an official language of every Member State where 4,4′-oxydianiline and its salts is placed on the market, unless that State has stated otherwise. This is the requirement most often missed by importers who hold a technically correct English document and assume it travels. A sheet in the wrong language is a refusal ground on its own, independent of the accuracy of its content.

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.

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.

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-[CAS?]. 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 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.
