N-[4-chloro-3-(trifluoromethyl)phenyl]-N-(phenylsulfonyl)benzenesulfonamide (CAS 854035-98-6), molecular formula C19H13ClF3NO4S2 and molecular weight 475.89 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-[4-chloro-3-(trifluoromethyl)phenyl]-N-(phenylsulfonyl)benzenesulfonamide (C19H13ClF3NO4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
