Structure search
Paste a SMILES or drawn structure first (or click Paste), then Search. A TimTec ID is optional when it exists — matches use SMILES. IDs with no SMILES still quote by ID.

Substructure / Similarity
Exact search works against in-stock catalog SMILES. Substructure and similarity need a chemistry index. This app does not run that index.
