Chemical Structure
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-(2-Chlorophenyl)-1H-1,2,4-triazole-3-thiol (CAS 58755-00-3), a certified reference material (molecular formula C8H6ClN3S, MW 211.67 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H6ClN3S, 5-(2-Chlorophenyl)-1H-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 211.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
