N-(3-Bromophenyl)-2-((5-(4-chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 476485-95-7

Description

N-(3-Bromophenyl)-2-((5-(4-chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 476485-95-7) is a high-purity analytical reference standard with the molecular formula C23H18BrClN4OS and a molecular weight of 513.84 g/mol.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, N-(3-Bromophenyl)-2-((5-(4-chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 513.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
