1-(2,4-Dichlorobenzyl)-3-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one CAS 477853-18-2 chemical structure

Description

The occurrence of 1-(2,4-Dichlorobenzyl)-3-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(2,4-Dichlorobenzyl)-3-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one (CAS 477853-18-2), a certified reference material (molecular formula C16H14Cl2N4OS, MW 381.28 g/mol) for analytical method development and quality control.

The molecular framework of 1-(2,4-Dichlorobenzyl)-3-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one (C16H14Cl2N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.

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.
