Description
CATO manufactures 5-[(4-bromophenyl)sulfamoyl]-2-chlorobenzoic 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.
5-[(4-bromophenyl)sulfamoyl]-2-chlorobenzoic acid (CAS 306764-81-8) is a high-purity analytical reference standard with the molecular formula C13H9BrClNO4S and a molecular weight of 390.64 g/mol.
The molecular framework of 5-[(4-bromophenyl)sulfamoyl]-2-chlorobenzoic acid (C13H9BrClNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
