Official sources for identity and EU status
PubChem compound record
Open the identity source for synonyms, structure, canonical SMILES, CAS context, and cross-registry identifiers.
globalPubChem PUG-REST
Primary open identity surface for broad molecule inventory expansion.
globalPubChem PUG-View
Useful when the site needs richer annotation text, hazard summaries, or evidence blocks beyond core identifiers.
EUECHA Candidate List
Official publication surface for substances of very high concern.
EUECHA SCIP
Best official starting point for SCIP duties, article-notification rules, and Waste Framework Directive context.
EUECHA SCIP Database
Searchable public database for SCIP article notifications under the Waste Framework Directive.
EUECHA Information on Chemicals
Best official starting point when a chemical needs a broader ECHA info layer beyond a single framework registry.
EUECHA Authorisation List
Use when a substance moves from watchlist interest to authorisation logic.
EUECHA POPs Regulation List
Important for legacy brominated flame retardants and high-risk persistence topics.
EUECHA CLH Intentions Registry
Useful for upcoming classification pressure even before an outcome page is curated.
EUECHA C&L Inventory
Useful for classification and labelling checks, hazard pressure, and CLP context around monitored chemicals.
USEPA CompTox Chemicals Dashboard
Secondary open source for cross-checking identifiers and screening context.
EUECHA Microplastics Topic Page
Relevant for cosmetics and formulation compliance questions.
