# InChI

The International Chemical Identifier (InChI) is a textual identifier for chemical substances developed by IUPAC and NIST. It encodes structural information in a standard layered format, and the hashed InChIKey provides a fixed-length string convenient for database searching and linking chemical records across resources.
