4-Bromo-5-chloro-N-(2,4-dimethoxybenzyl)-2-fluoro-N-(thiazol-2-yl)benzenesulfonamide (CAS 2342604-44-6), molecular formula C18H15BrClFN2O4S2 and molecular weight 521.81 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-5-chloro-N-(2,4-dimethoxybenzyl)-2-fluoro-N-(thiazol-2-yl)benzenesulfonamide (C18H15BrClFN2O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
