WebSep 18, 2012 · The goal of the InChI is to provide an canonical representation that can be used to link information from different databases on the same molecules. To do this, the InChI algorithm combines a normalisation procedure, a canonicalisation algorithm, and a layered structure that helps identify isomers. WebThe IUPAC International Chemical Identifier (InChI) is a freely available, nonproprietary identifier for chemical substances that can be used in both printed and electronic data sources. It is generated from a computerized representation of a molecular structure diagram, produced by chemical structure-drawing software.
Information from the InChI
WebInChI Keys are generated using algorithms that take into account the structure of the chemical compound, including its atoms, bonds, and other structural features. The InChI Key is intended to be a unique identifier for a chemical compound, meaning that no two chemical compounds should have the same InChI Key.

International Chemical Identifier - Wikipedia
WebSparteine is a plant alkaloid derived from Cytisus scoparius and Lupinus mutabilis which may chelate calcium and magnesium.It is a sodium channel blocker, so it falls in the category of class 1a antiarrhythmic agents. Sparteine is not currently FDA-approved for human use, and its salt, sparteine sulfate, is one of the products that have been … The International Chemical Identifier is a textual identifier for chemical substances, 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 … See more In order to avoid generating different InChIs for tautomeric structures, before generating the InChI, an input chemical structure is normalized to reduce it to its so-called core parent structure. This may involve changing … See more Every InChI starts with the string "InChI=" followed by the version number, currently 1. If the InChI is standard, this is followed by the letter S for standard InChIs, which is a fully standardized InChI flavor maintaining the same level of attention to structure details and … See more Scientific direction of the InChI standard is carried out by the IUPAC Division VIII Subcommittee, and funding of subgroups investigating and defining the expansion of the standard is carried out by both IUPAC and the InChI Trust. The InChI Trust funds the … See more • Molecular Query Language • Simplified molecular-input line-entry system (SMILES) • Molecule editor • SYBYL Line Notation • Bioclipse generates InChI and InChIKeys for drawn structures or opened files See more The condensed, 27 character InChIKey is a hashed version of the full InChI (using the SHA-256 algorithm), designed to allow for easy web searches of chemical compounds. The … See more The format was originally called IChI (IUPAC Chemical Identifier), then renamed in July 2004 to INChI (IUPAC-NIST Chemical Identifier), and renamed again in November 2004 to … See more The InChI has been adopted by many larger and smaller databases, including ChemSpider, ChEMBL, Golm Metabolome Database See more WebCAS Common Chemistry is provided under the Creative Commons Attribution-NonCommercial 4.0 International License, or CC BY-NC 4.0 license.
