InChI and InChIKeys for chemical structures
The InChI Trust is a nonprofit charity which works to develop and promote the use of the IUPAC InChI open-source chemical structure representation algorithm.
The InChI with its associated InChIKey was developed as a non-proprietary international standard to represent chemical structures and has just celebrated its tenth anniversary. The Trust aims to develop and improve on the current InChI standard, further enabling the interlinking of chemistry and chemical structures on the web.
The Trust will be holding an InChI Symposium ahead of the ACS National Meeting in San Diego, on 23-24 August 2019. The event will include a mix of themed talks on use cases and working breakout sessions. Short talks around use cases especially welcome, so please indicate in the event sign-up if you would like to be a speaker. Register for the symposium
