How we work

The InChI Trust is a charity that supports the development and promotion of the InChI standard. It works in partnership with IUPAC to update and release new extensions to and applications of InChI. The Trust is a membership organisation, governed by its Board of Trustees which includes representation from IUPAC.

The scientific design of the various tools and capabilities that comprise the InChI code are defined by the InChI Working Groups which are made up of volunteers from the InChI community with IUPAC oversight. These voluntary groups are each focused on specific areas of chemistry or tools within the InChI code. See Working Groups for details on each group and their membership.

The development of the code is coordinated by the Technical Director of the InChI Trust, together with the working groups, IUPAC and our development partners. Our development partners currently include RWTH Aachen (as part of NFDI4Chem, acknowledging funding from Volkswagen Stiftung and the Data Literacy Alliance – DALIA), and the Beilstein-Institut.

Explain that InChI (4 November 2026)

Our colleagues at the Beilstein-Institut have built an open-source, browser-based tool to explore and help understand what an InChI means. Draw or upload a molecule and it generates the InChI, color-codes each layer, and explains it
