Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-4-chloro-N-{4-[(difluoromethyl)sulfanyl]phenyl}benzene-1-sulfonamide.
3-Amino-4-chloro-N-{4-[(difluoromethyl)sulfanyl]phenyl}benzene-1-sulfonamide (CAS 325732-19-2), molecular formula C13H11ClF2N2O2S2 and molecular weight 364.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-4-chloro-N-{4-[(difluoromethyl)sulfanyl]phenyl}benzene-1-sulfonamide (C13H11ClF2N2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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 its high hydrophobicity (logP), 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.
CATO manufactures 3-Amino-4-chloro-N-{4-[(difluoromethyl)sulfanyl]phenyl}benzene-1-sulfonamide 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.
