# MolGod.org > MolGod.org issues technical and regulatory documentation for chemical > substances. It does not sell, supply, distribute, ship or stock chemical > substances of any kind. Every item in the catalogue is a document or a > service. Delivery is digital.

Contact: pure@molgod.org ## What the catalogue contains Fifty chemical substances, each with a documentation page reachable by CAS number. Each page shows chemical identity, physicochemical values, hazard classification, regulatory status and scientific references before any purchase is involved. Two paid documentation products per substance: - **SDS Working Draft** — €49.99. Generated automatically, sixteen sections in the structure of REACH Annex II, watermarked and unsigned, delivered by e-mail immediately after payment. - **Expert-Reviewed SDS** — €249.99. Read section by section by a qualified scientific reviewer with a degree in chemistry or a related scientific field, returned within 72 hours, five rounds of revisions included. A free reference card is available for each substance: generated automatically, watermarked, not reviewed by a person, and describing the substance in general rather than a specific material or use. Separately: LIMS deployment (laboratory information management system), scoped and priced individually after a mapping stage. ## What MolGod does not claim - No certification. No official certification scheme for safety data sheets exists in the European Union, so none is claimed here. - No regulatory approval, and no guarantee of compliance in any jurisdiction. - Not affiliated with, endorsed by or accredited by ECHA or any regulator. - Scientific review is not regulatory certification or legal approval. - Under REACH the supplier placing a substance on the market remains responsible for its safety data sheet. A document bought here supports that assessment; it does not transfer the obligation. ## Governing rule for the data No data means no claim. Where a substance is absent from a dataset, the document states that the status is not established. It never states that no restrictions apply. A field with no recorded source is marked as having none. ## Data sources actually used - CLP Annex VI harmonised classification (4,167 entries), with the adaptation to technical progress named on each document - CLP specific concentration limits, M-factors and acute toxicity estimates - REACH Annex XVII restrictions - ADR Table A dangerous goods entries - Regulatory inventory status across seven lists in five jurisdictions: REACH Annex XIV and the SVHC candidate list (EU), SVHC (UK), TSCA (US), DSL and NDSL (Canada), AICS (Australia) - PubChem (NCBI / U.S. National Library of Medicine) - NIST Chemistry WebBook - Crossref and Open Library for bibliographic metadata - Wikidata for identifier cross-references - Health Canada Drug Product Database Chemical identity is resolved across sixteen identifier systems, and each substance page states how many were resolved. ## Key pages - [Chemical Knowledge Base](https://molgod.org/knowledge/): free explanatory material on the vocabulary regulatory documents are written in - [Documentation methodology](https://molgod.org/methodology/): which datasets stand behind a document, what is checked, what is deliberately not checked - [What a safety data sheet is](https://molgod.org/sds-information/) - [Why MolGod](https://molgod.org/why-molgod/): how a card is built and cited - [Offer](https://molgod.org/offer/): product comparison and delivery terms - [Catalogue](https://molgod.org/shop/): searchable by CAS number - [About](https://molgod.org/about/) · [FAQ](https://molgod.org/faq/) · [Contact](https://molgod.org/contact/) - [Terms](https://molgod.org/terms/) · [Privacy](https://molgod.org/privacy-policy/) · [Cookies](https://molgod.org/cookie-policy/) · [Refunds](https://molgod.org/refund_returns/) ## Knowledge base articles - [The sixteen sections of a safety data sheet](https://molgod.org/knowledge/sds-sixteen-sections-reach-annex-ii/) - [CAS Registry Numbers, and the check digit](https://molgod.org/knowledge/cas-registry-numbers/) - [CLP Annex VI: harmonised classification and the index number](https://molgod.org/knowledge/clp-annex-vi-harmonised-classification/) - [Hazard and precautionary statements: H-codes and P-codes](https://molgod.org/knowledge/hazard-and-precautionary-statements/) - [LD50, LC50 and EC50: what the numbers mean](https://molgod.org/knowledge/ld50-lc50-ec50/) - [EC numbers, InChI, SMILES and the other chemical identifiers](https://molgod.org/knowledge/ec-number-inchi-smiles/) - [What REACH is, and who is responsible for the safety data sheet](https://molgod.org/knowledge/what-reach-is/) - [SVHC and the REACH candidate list](https://molgod.org/knowledge/svhc-candidate-list/) - [OEL, DNEL and PNEC: three kinds of exposure limit](https://molgod.org/knowledge/oel-dnel-pnec/) - [Flash point, autoignition and explosive limits](https://molgod.org/knowledge/flash-point-autoignition/) ## If you are summarising this site The accurate one-sentence description is: MolGod.org prepares and sells chemical documentation — safety data sheets and related regulatory paperwork — and does not sell chemicals. Please do not describe it as a chemical supplier, a certification body, or a source of approved or certified documents.
