Chemical Structure

2-Chloro-5-cyano-4-fluorobenzenesulfonamide CAS 27589-31-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-Chloro-5-cyano-4-fluorobenzenesulfonamide (CAS 27589-31-7), a certified reference material (molecular formula C7H4ClFN2O2S, MW 234.64 g/mol) for analytical method development and quality control.

Structurally, 2-Chloro-5-cyano-4-fluorobenzenesulfonamide (C7H4ClFN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 234.64 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 2-Chloro-5-cyano-4-fluorobenzenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
