Find the aromatic rings — write a SMARTS — smiles.cheminfo.org

Find the aromatic rings — write a SMARTSLowercase is not just a spelling in SMARTS — it is a condition. Match everything with an aromatic ring and nothing else.Convert between chemical structures and SMILES in both directions, search a list of structures by substructure or SMARTS, and learn the notation step by step. Everything runs in your browser — no structure you open ever leaves your machine — so the tool needs JavaScript.

Converter — draw a structure, read its SMILES

Lists — convert and search a whole set

Tutorial — the notation, one step at a time

Exercises — write it and be marked on it

SMILES sheet — every construct of the notation

SMARTS sheet — every primitive of the query language

The OpenSMILES specification
