RInChI: a chemical identifier for reactions

The aim of the RInChI Project is to create a unique, canonical, text string to describe a reaction. Different researchers working on the same reaction should be able to generate the same RInChI without needing to confer with each other


The latest software can be downloaded from the InChI Trust website


A program to generate QR Codes from InChIKeys and search for information about the corresponding molecules is also available:
