Chemical Structure
Description
3-Chloro-4-(3-(4-hydroxyphenyl)-5-oxoimidazolidin-1-yl)benzenesulfonamide (CAS 65653-83-0) is a high-purity analytical reference standard with the molecular formula C15H14ClN3O4S and a molecular weight of 367.81 g/mol.
The molecular framework of 3-Chloro-4-(3-(4-hydroxyphenyl)-5-oxoimidazolidin-1-yl)benzenesulfonamide (C15H14ClN3O4S) 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).
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.
CATO manufactures 3-Chloro-4-(3-(4-hydroxyphenyl)-5-oxoimidazolidin-1-yl)benzenesulfonamide 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.
