N-(2-Bromo-4-methylphenyl)-2-((4-ethyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 482639-70-3) is a high-purity analytical reference standard with the molecular formula C18H18BrN5OS and a molecular weight of 432.34 g/mol.

The molecular framework of N-(2-Bromo-4-methylphenyl)-2-((4-ethyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C18H18BrN5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 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).

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.
