1-(3-Chlorobenzyl)-3-(1-methyl-5-thioxo-2,5-dihydro-1H-1,2,4-triazol-3-yl)pyridin-2(1H)-one CAS 242472-29-3

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.

1-(3-Chlorobenzyl)-3-(1-methyl-5-thioxo-2,5-dihydro-1H-1,2,4-triazol-3-yl)pyridin-2(1H)-one (CAS 242472-29-3) is a high-purity analytical reference standard with the molecular formula C15H13ClN4OS and a molecular weight of 332.81 g/mol.

The molecular framework of 1-(3-Chlorobenzyl)-3-(1-methyl-5-thioxo-2,5-dihydro-1H-1,2,4-triazol-3-yl)pyridin-2(1H)-one (C15H13ClN4OS) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
