Chemical Structure

1-Benzyl-3-(4-methyl-5-(prop-2-yn-1-ylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one CAS 282523-21-1 chemical structure

Description

1-Benzyl-3-(4-methyl-5-(prop-2-yn-1-ylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one (CAS 282523-21-1) is a high-purity analytical reference standard with the molecular formula C18H16N4OS and a molecular weight of 336.41 g/mol.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-Benzyl-3-(4-methyl-5-(prop-2-yn-1-ylthio)-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
