2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-1-(3,4-dichlorophenyl)ethanone CAS 578000-53-0

Description

The molecular framework of 2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-1-(3,4-dichlorophenyl)ethanone (C21H13BrCl2N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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).

2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-1-(3,4-dichlorophenyl)ethanone (CAS 578000-53-0) is a high-purity analytical reference standard with the molecular formula C21H13BrCl2N4OS and a molecular weight of 520.23 g/mol.

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.
