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 2,5-Dichloro-N-(2-((3-cyano-4,6-dimethylpyridin-2-yl)thio)phenyl)benzenesulfonamide (CAS 478033-64-6), a certified reference material (molecular formula C20H15Cl2N3O2S2, MW 464.39 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2,5-Dichloro-N-(2-((3-cyano-4,6-dimethylpyridin-2-yl)thio)phenyl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2,5-Dichloro-N-(2-((3-cyano-4,6-dimethylpyridin-2-yl)thio)phenyl)benzenesulfonamide 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.
