4-(4-Methoxyphenyl)-5-(4-nitrophenyl)-4H-1,2,4-triazole-3-thiol CAS 17050-55-4

Description

The occurrence of 4-(4-Methoxyphenyl)-5-(4-nitrophenyl)-4H-1,2,4-triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(4-Methoxyphenyl)-5-(4-nitrophenyl)-4H-1,2,4-triazole-3-thiol (CAS 17050-55-4), a certified reference material (molecular formula C15H12N4O3S, MW 328.35 g/mol) for analytical method development and quality control.

The molecular framework of 4-(4-Methoxyphenyl)-5-(4-nitrophenyl)-4H-1,2,4-triazole-3-thiol (C15H12N4O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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.
