The IUPAC International Chemical Identifier (InChI)

The International Chemical Identifier is a textual identifier for chemical substances, designed to provide a standard way to encode molecular information and to facilitate the search for such information in databases and on the web. Initially developed by the International Union of Pure and Applied … See more In order to avoid generating different InChIs for tautomeric structures, before generating the InChI, an input chemical structure is normalized to reduce it to its so-called core parent structure. This may involve changing … See more Every InChI starts with the string "InChI=" followed by the version number, currently 1. If the InChI is standard, this is followed by the letter S for standard InChIs, which is a fully standardized … See more The format was originally called IChI (IUPAC Chemical Identifier), then renamed in July 2004 to INChI (IUPAC-NIST Chemical Identifier), and renamed again in November 2004 to InChI (IUPAC International Chemical Identifier), a trademark of IUPAC.

WebInChI Keys are generated using algorithms that take into account the structure of the chemical compound, including its atoms, bonds, and other structural features. The InChI Key is intended to be a unique identifier for a chemical compound, meaning that no two chemical compounds should have the same InChI Key. song lyrics dont ask me if im still in love
