5-(4-Tert-butylphenyl)-4-(4-methoxyphenyl)-4h-1,2,4-triazole-3-thiol CAS 713098-07-8

Description

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.

5-(4-Tert-butylphenyl)-4-(4-methoxyphenyl)-4h-1,2,4-triazole-3-thiol (CAS 713098-07-8) is a high-purity analytical reference standard with the molecular formula C19H21N3OS and a molecular weight of 339.45 g/mol.

The molecular framework of 5-(4-Tert-butylphenyl)-4-(4-methoxyphenyl)-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
