Chemical Name and Structure Conversion

A reliable tool to convert a variety of chemical names into structures and vice-versa

ChemAxon offers a powerful naming engine that can convert chemical and biochemical structures and names into various formats bi-directionally. In addition to IUPAC and traditional name support, it recognizes common names and CAS registry numbers. It references a local user customizable dictionary, a database or a web service to convert corporate IDs, or arbitrary texts to structures. Besides English language, our technology supports name to structure conversion from Chinese and Japanese languages as well.

Structure to Name Conversion – IUPAC and common names

Naming allows users to generate an IUPAC names from structures according to the latest IUPAC conventions. In addition, traditional names can also be generated if applicable. Radicals, natural products, or peptide sequences are also supported.

Customizable Dictionary

ChemAxon's naming technology is highly flexible and customizable. The chemical name and structure conversion supports users custom dictionary, where SMILES and any other text can be used to reference information for conversion. This is rather useful if there are obscure common names that cannot be found in our naming dictionary, or if corporate compound IDs have to be converted into chemical structures. This custom dictionary can be stored in a local file, accessed from a database, or through a web service.
