4-((4-Ethoxy-3-methoxybenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione CAS 478256-21-2

Description

4-((4-Ethoxy-3-methoxybenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-21-2) is a high-purity analytical reference standard with the molecular formula C19H20N4O2S and a molecular weight of 368.45 g/mol.

Based on its molecular formula C19H20N4O2S, 4-((4-Ethoxy-3-methoxybenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.45 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).

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.
