Chemical Structure
Description
The occurrence of 4-Chloro-N-((4-chlorophenyl)sulfonyl)-N-(3,5-di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)benzenesulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-N-((4-chlorophenyl)sulfonyl)-N-(3,5-di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)benzenesulfonamide (CAS 338395-21-4), molecular formula C24H16Cl2N6O4S2 and molecular weight 587.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-N-((4-chlorophenyl)sulfonyl)-N-(3,5-di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)benzenesulfonamide (C24H16Cl2N6O4S2) 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. 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.
