Section 9 — physicochemical properties: 7 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.

DOCUMENTATION AND 3D PRINTED MODELS ONLY

This page offers documentation related to the listed substance. MolGod does not sell or supply the chemical substance itself.

  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”.

About the language versions

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.

⚠ Classification based on a consensus of sources (PubChem / supplier notifications) — not verified against the harmonised classification in Annex VI (CLP). The scope of hazards may be broader than the official classification; verify against the supplier's current safety data sheet before use.

⚠ IARC — Group 2B: possibly carcinogenic to humans. (Independent assessment of carcinogenicity evidence by IARC/WHO — supplements the CLP classification above.)

⚠️ Ionic / inorganic compound — Hansen parameters (δD/δP/δH) do not apply: dissolution is governed by crystal-lattice energy and ion solvation, not molecular cohesion. The HSP block and Hansen sphere are omitted. HSP-dependent columns (Compat./Ra/Visual) are marked "n/a" — base solvent selection on experimental data.

Solvent compatibility table not available for this substance.
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.

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.
