A Technology Breakthrough

NamExpert understands IUPAC organic nomenclature rules. If you enter an IUPAC chemical name, it creates the corresponding structure in one of the three styles: shorthand, Kekule, or semistructural formula. It adds labels to appropriate atoms and groups. The new version now supports stereochemistry, and includes 8000 drug names and structures.

NamExpert is fully integrated with Chemistry 4-D Draw. It is also available as an add-on for CS ChemDraw. Its sister product, Nomenclator assigns systematic names to structures according to IUPAC nomenclature rules.

NamExpert Database

NamExpert Database automatically converts a large number of names to structures. NamExpert Database allows you to run NamExpert in either batch mode or interactive mode to convert a database of names to structures. The input file is an ASCII file and the output file is a MDL SD file. You can generates tens of thousands of structures within hours.
