1-Ethyl-3-(5-mercapto-4-methyl-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one CAS 1105196-08-4

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.

CATO supplies 1-Ethyl-3-(5-mercapto-4-methyl-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one (CAS 1105196-08-4), a certified reference material (molecular formula C10H12N4OS, MW 236.29 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-Ethyl-3-(5-mercapto-4-methyl-4H-1,2,4-triazol-3-yl)pyridin-2(1H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
