The '''International Chemical Identifier''' ('''InChI''', <small>pronounced</small> {{IPAc-en|ˈ|ɪ|n|tʃ|iː}} {{respell|IN|chee}} or )<ref>{{IPAc-encite web |ˈtitle=What on Earth is InChI? |ɪ|ŋurl=https://iupac.org/100/stories/what-on-earth-is-inchi/ |k|iː}}website=IUPAC 100 {{respell|ING|keeaccess-date=10 May 2024}})</ref> is a textual [[identifier]] for [[chemical substance]]s, designed to provide a standard way to encode molecular information and to facilitate the search for such information in databases and on the web. Initially developed by the [[International Union of Pure and Applied Chemistry]] (IUPAC) and [[National Institute of Standards and Technology]] (NIST) from 2000 to 2005, the format and algorithms are non-proprietary. Since May 2009, it has been developed by the InChI Trust, a nonprofit charity from the [[United Kingdom]] which works to implement and promote the use of InChI.<ref>{{Cite web |title=The InChI Trust and IUPAC |url=https://www.inchi-trust.org/iupac/ |access-date=August 22, 2022 |publisher=InChI Trust}}</ref>
