4-Chloro-N-[(5-{[(4-chlorophenyl)methyl]sulfanyl}-4-methyl-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide CAS 338421-49-1 chemical structure

Description

CATO manufactures 4-Chloro-N-[(5-{[(4-chlorophenyl)methyl]sulfanyl}-4-methyl-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide 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.

CATO supplies 4-Chloro-N-[(5-{[(4-chlorophenyl)methyl]sulfanyl}-4-methyl-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide (CAS 338421-49-1), a certified reference material (molecular formula C17H16Cl2N4O2S2, MW 443.37 g/mol) for analytical method development and quality control.

The molecular framework of 4-Chloro-N-[(5-{[(4-chlorophenyl)methyl]sulfanyl}-4-methyl-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide (C17H16Cl2N4O2S2) is characterized by a steroid 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.
