Yes. Use the REST source type with the PubChem PUG REST API and a per-compound CID or CAS lookup. Cache the responses with a long duration since foundational compound data rarely changes. A hybrid approach is common: PubChem fields for foundational data, a sheet for editorial overrides like preferred descriptions and curated synonyms.

For 2D, store a SMILES string and use RDKit-JS or a server-side render of an SVG. For 3D, store a MOL file URL and embed a 3Dmol.js viewer. Selector mapping injects either form into a placeholder in the template. Lazy-load the 3D viewer so it does not slow the initial paint.

Maintain GHS pictograms and H-codes in arrays per row, referencing the official GHS revision your jurisdiction follows. When GHS gets revised, update the affected rows in the sheet and every page refreshes on the next cache cycle. Cite the SDS source per compound in a references column for auditability.

Yes. Each URL is added to the SleekRank sitemap. The base template is excluded and noindexed. Submit the sitemap in Search Console. Common compound queries face strong SERP competition; the long tail of specific property queries, CAS lookups, and synonyms is far easier and represents most of the corpus value.

Yes. Maintain language-specific columns for name, iupac_name, description, and uses, or maintain separate sources per language routed via different URL patterns. CAS numbers and formulas stay constant across languages but everything else benefits from translation.

If you also publish reactions, build a reactions page group with reactants and products arrays referencing compound slugs. List mapping on the compound page can show a sample of reactions where it appears by reading filtered rows from the reactions source. The reverse direction works the same way.

Yes. Store a synonyms array per row and render it into a visible list. Search engines index the synonyms as page content, which captures queries that use trade names or older nomenclature. For pharmaceuticals especially, brand names and generic names should both live in the array.

No. Property values come from the source. SleekRank only injects what is in the data. Compound properties need to be sourced from authoritative references like NIST, PubChem, or the SDS; SleekRank handles publishing and ensures consistency, not data origination.
