trinickel disulfide (CAS 12035-72-2) — Safety Data Sheet

Safety data sheet documentation for trinickel disulfide (CAS 12035-72-2), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H350i, H341, H331, H372). 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.

  3. €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 you receive — and what this is not

What you receive

  • 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.

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.

For trinickel disulfide (CAS 12035-72-2) the documentation obligation begins before the first shipment. This page sets out what the safety data sheet has to establish.

How is trinickel disulfide classified for road, sea and air transport?

Carriers and forwarders handling trinickel disulfide compare section 14 against the shipping papers before loading. Any disagreement stops the consignment at the point where correcting it is most expensive.

What must the label for trinickel disulfide contain?

The supply label for trinickel disulfide 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 H350i, H341, H331… 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.

What is the CLP classification of trinickel disulfide?

The harmonised classification for CAS 12035-72-2 carries 7 hazard statements: H350i, H341, H331, H372, H317, H400, H410. In plain terms this means H350i; suspected of causing genetic defects; toxic if inhaled; causes damage to organs through prolonged or repeated exposure. 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.

Can I import trinickel disulfide into the EU?

Bringing trinickel disulfide into the Union is a documentation exercise before it is a logistics one. The file has to exist at the moment of import, not at the moment somebody asks for it, and for nickel compounds it is examined in the context of metal-compound consignments under authorisation pressure. Index 028-007-00-4 fixes the classification that section 2 must reproduce.

What is the EC number for trinickel disulfide?

Alongside CAS 12035-72-2, this substance carries EC number 234-829-6 [1];- [2] and Annex VI index 028-007-00-4. 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.

Where is regulatory status recorded for trinickel disulfide?

Whether CAS 12035-72-2 carries obligations beyond classification — candidate list entry, authorisation, restriction — belongs in section 15. Customers increasingly request a written statement on this point before placing an order, and the sheet is the natural place for it.

Target organ toxicity in the sheet

Specific target organ toxicity (H372) obliges the sheet to state the route of exposure and, where established, the organ affected. This is one of the few places where a generic phrase is treated as a defect rather than as caution: an unspecified organ leaves the downstream user unable to build an exposure scenario.

What concentration limits apply to trinickel disulfide?

Acute toxicity estimate stated in the register: inhalation: ATE = 0,92 mg/l.

Stability, reactivity and incompatibilities

The reactivity information for CAS 12035-72-2 provided under Section 10 must be sufficiently detailed and actionable. While stating ‘avoid strong oxidizing agents’ offers a general category, specifying the exact chemical classes that react with the substance in question provides clearer guidance on appropriate handling and precautionary measures.

Disposal route and waste classification

Section 13 for CAS 12035-72-2 outlines the disposal method and procedures for contaminated packaging. Laboratories are subject to audits to ensure their waste management practices align with the information provided in this section. Any ambiguity or lack of specificity in this section may result in findings against the laboratory rather than the supplier, as it is responsible for adhering to the declared waste stream.

Is trinickel disulfide classified as a CMR substance?

CAS 12035-72-2 is classified as a CMR substance (H350i). 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.

Identifiers that must agree

Identity verification must be conducted prior to hazard assessment. If discrepancies exist between the label, safety data sheet, and certificate regarding the CAS 12035-72-2 number or if the index 028-007-00-4 refers to a location where the name does not match, a reviewer will lose trust in all three documents simultaneously, despite their internal consistency. This is because inconsistencies among these key documentation elements undermine their reliability as a unified source of information.

What Annex VI notes and concentration limits apply to trinickel disulfide?

The register also records inhalation: ATE = 0.92 mg/L dusts or mists for this entry. Specific concentration limits, M-factors and acute toxicity estimates override the generic cut-off values, so a mixture calculation that ignores them will classify the mixture wrongly in both directions.

Which GHS pictograms apply to trinickel disulfide?

The label for trinickel disulfide 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 12035-72-2, 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.

Protective equipment and exposure controls

When conducting a risk assessment for trinickel disulfide, laboratories must begin by referring to Section 8. If an occupational exposure limit is in place, it is essential to clearly state this limit along with its source and the corresponding averaging period. In cases where no such limit exists, the documentation should explicitly indicate this fact rather than leaving the relevant field blank.

Questions about documentation for trinickel disulfide

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 trinickel disulfide 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 trinickel disulfide?

CAS 12035-72-2. In CLP Annex VI the same substance carries index number 028-007-00-4, and both identifiers should appear in the documentation.

Is trinickel disulfide 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.

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
