5-(4-Bromo-phenoxymethyl)-4-(4-ethoxy-phenyl)-4H-[1,2,4]triazole-3-thiol CAS 522624-65-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-Bromo-phenoxymethyl)-4-(4-ethoxy-phenyl)-4H-[1,2,4]triazole-3-thiol.

CATO supplies 5-(4-Bromo-phenoxymethyl)-4-(4-ethoxy-phenyl)-4H-[1,2,4]triazole-3-thiol (CAS 522624-65-3), a certified reference material (molecular formula C17H16BrN3O2S, MW 406.30 g/mol) for analytical method development and quality control.

Structurally, 5-(4-Bromo-phenoxymethyl)-4-(4-ethoxy-phenyl)-4H-[1,2,4]triazole-3-thiol (C17H16BrN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 406.30 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
