4-(3-Chloro-4-methyl-phenyl)-5-(4-chloro-phenyl)-4H-[1,2,4]triazole-3-thiol CAS 380346-36-1

Description

The occurrence of 4-(3-Chloro-4-methyl-phenyl)-5-(4-chloro-phenyl)-4H-[1,2,4]triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(3-Chloro-4-methyl-phenyl)-5-(4-chloro-phenyl)-4H-[1,2,4]triazole-3-thiol (CAS 380346-36-1), a certified reference material (molecular formula C15H11Cl2N3S, MW 336.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H11Cl2N3S, 4-(3-Chloro-4-methyl-phenyl)-5-(4-chloro-phenyl)-4H-[1,2,4]triazole-3-thiol contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
