4-((3-Ethoxy-4-hydroxybenzylidene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione CAS 613249-73-3

Description

Compared with other compounds in its class, the molecular weight of 384.45 g/mol gives 4-((3-Ethoxy-4-hydroxybenzylidene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-((3-Ethoxy-4-hydroxybenzylidene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 613249-73-3), a certified reference material (molecular formula C19H20N4O3S, MW 384.45 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-((3-Ethoxy-4-hydroxybenzylidene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.45 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.
