2-(4-Ethyl-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine CAS 578748-19-3

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.

2-(4-Ethyl-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 578748-19-3), molecular formula C17H18N4S and molecular weight 310.42 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H18N4S, 2-(4-Ethyl-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine 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 310.42 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.
