Chemical Structure

4-(2,3-Dimethylphenyl)-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol CAS 917748-23-3 chemical structure

Description

The molecular framework of 4-(2,3-Dimethylphenyl)-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol (C19H21N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-(2,3-Dimethylphenyl)-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol (CAS 917748-23-3), molecular formula C19H21N3OS and molecular weight 339.45 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
