Methodology

This list starts with well-known carbon-containing compounds across major functional classes. PubChem provides canonical identifiers and SMILES; ChEBI and ChEMBL are recommended for expanded class and bioactivity annotations.

Expansion plan

Expand by functional class and provide filtered downloads for alkanes, alkenes, aromatics, alcohols, aldehydes, ketones, acids, esters, amines, amides, and heterocycles.
