2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(4-methoxyphenyl)acetamide (CAS 332934-90-4) is a high-purity analytical reference standard with the molecular formula C23H19BrN4O2S and a molecular weight of 495.39 g/mol.
2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(4-methoxyphenyl)acetamide (C23H19BrN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
