Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 2-((4-(4-Bromophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-chloro-4-methylphenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 514.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-((4-(4-Bromophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-chloro-4-methylphenyl)acetamide (CAS 477329-38-7) is a high-purity analytical reference standard with the molecular formula C22H17BrClN5OS and a molecular weight of 514.83 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.
