2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide CAS 332388-18-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide.

2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide (CAS 332388-18-8), molecular formula C23H19BrN4OS and molecular weight 479.39 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 479.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
