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.

trust November 10, 2021: We sadly note the passing of Igor Pletnev

Igor Pletnev was the developer and caretaker of the InChI software algorithm for over 15 years, first at NIST and then at the InChI Trust. Over the years Igor made great contributions to the InChI project. His knowledge of both chemistry and computer programming made him a unique person to carry out all these tasks while interacting with chemists around the world on an almost daily basis. While there were many demands on his work efforts with the InChI algorithm, Igor always was calm and friendly to all, a true professional at all times. He will be missed and dearly remembered for all of his outstanding work by all of us at InChI Trust and the global community of InChI developers and users.
