Chemical Structure

2-Chloro-n-(4h-1,2,4-triazol-3-yl)benzenesulfonamide CAS 1024117-48-3 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

CATO supplies 2-Chloro-n-(4h-1,2,4-triazol-3-yl)benzenesulfonamide (CAS 1024117-48-3), a certified reference material (molecular formula C8H7ClN4O2S, MW 258.68 g/mol) for analytical method development and quality control.

The molecular framework of 2-Chloro-n-(4h-1,2,4-triazol-3-yl)benzenesulfonamide (C8H7ClN4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
