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 4-Chloro-3-(2,5-dichloro-phenylsulfamoyl)-benzoic acid.
CATO supplies 4-Chloro-3-(2,5-dichloro-phenylsulfamoyl)-benzoic acid (CAS 327092-97-7), a certified reference material (molecular formula C13H8Cl3NO4S, MW 380.63 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-3-(2,5-dichloro-phenylsulfamoyl)-benzoic acid (C13H8Cl3NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 4-Chloro-3-(2,5-dichloro-phenylsulfamoyl)-benzoic acid 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.
