About the InChI Trust
The InChI Trust is a nonprofit UK charity which works to implement 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; the Trust aims to support the development and improve on the current InChI standard, further enabling the interlinking of chemistry and chemical structures on the web.
The charitable objects of the InChI Trust are the advancement of science for the public benefit, in particular by:
- Developing, reviewing and disseminating the internationally agreed standard representation, the IUPAC InChI, of defined chemical structure and their links to related information;
- Developing an organisational framework for implementation of and compliance with such codes of practice;
- Contributing to the use and understanding of chemical structure standards and related information
