The InChI algorithm converts input structural information into a unique InChI identifier in a three-step process: normalization (to remove redundant information), canonicalization (to generate a unique …

This paper documents the design, layout and algorithms of the IUPAC International Chemical Identifier, InChI. (older news and journal articles on the Identifier are listed for archives purpose).

The scientific design of the various tools and capabilities that comprise the InChI code are defined by the InChI Working Groups which are made up of volunteers from the InChI community with IUPAC …

If searching on an InChI string, please enter the full identifier string, including the “InChI=” portion. Please note that this search will only find species which have structures in the database.

Since its public introduction in 2005 the IUPAC InChI chemical structure identifier standard has become the international, worldwide standard for defined chemical structures.

InChIs are International Chemical Identifiers, developed by the International Union of Pure and Applied Chemistry (IUPAC). They are a text representation of molecule information that is in a human …
