Chemical Structure
Description
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.
5-[benzyl(4-methoxyphenyl)sulfamoyl]-2-chlorobenzoic acid (CAS 565198-70-1), molecular formula C21H18ClNO5S and molecular weight 431.89 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-[benzyl(4-methoxyphenyl)sulfamoyl]-2-chlorobenzoic acid (C21H18ClNO5S) is characterized by a flavonoid core, 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. 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 5-[benzyl(4-methoxyphenyl)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.
