November 7, 2022: Planning a Full InChI Projects Review at Fall ACS 2023 in San Francisco

We are planning a full day review of all of the active InChI projects at the Fall 2023 ACS meeting in San Francisco. The InChI Review will take place on Saturday Aug 12, 2023. The location in San Francisco will be finalized on the coming weeks. It will be a hybrid meeting with remote participation.

Each active Working Group will provide an update and an overview of future plans.

This symposium honoring the many contributions of Igor Pletnev to the InChI project was held as part of the ACS Chicago 2022 meeting on Sunday August 21. Also covered were many research and development efforts to extend the InChI standard into additional areas of chemistry. The slide decks for these presentations are now available here.

SciFinder Search Substances Expanded to Include Searching With InChI Key

Chemicl Abstracts Service announced that they have added an Advanced Search Field to search substances by InChI Key to SciFinder. InChI Key was added to a new Chemical Identifier subsection along with Chemical Name. Multiple entries must be delimited by a comma, space, or semicolon.

general April 7, 2022: InChI Days 2022 Symposium

Our InChI Days 2022 virtual symposium brought together much of the InChI development community to discuss directions and future evolution of the InChI Standard. While the InChI Standard is quite stable and used across much of the organic chemistry space, our symposium covered a wide and diverse suite of extensions being studied by working groups of experts in each area. Topics covered by these teams at our meeting included extended stereochemistry, extended tautomers, polymers, Markush/variable structures, mixtures, reactions, nanomamaterials, isotopologues and the use of QR codes. We have the slide decks from the sessions available on our website ( If you are interested in InChI or any of these extensions, sign up for our newsletter InChI OUTREACH: SUBSCRIBE to InChI OUTREACH.
