5-Methyl-4-phenyl-4H-1,2,4-triazol-3-yl hydrosulfide CAS 6232-82-2

Description

CATO supplies 5-Methyl-4-phenyl-4H-1,2,4-triazol-3-yl hydrosulfide (CAS 6232-82-2), a certified reference material (molecular formula C9H9N3S, MW 191.25 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H9N3S, 5-Methyl-4-phenyl-4H-1,2,4-triazol-3-yl hydrosulfide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.25 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.
