5-(3-Chlorobenzyl)-4-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thione CAS 791717-23-2

Description

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.

CATO supplies 5-(3-Chlorobenzyl)-4-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 791717-23-2), a certified reference material (molecular formula C15H12ClN3S, MW 301.79 g/mol) for analytical method development and quality control.

5-(3-Chlorobenzyl)-4-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (C15H12ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
