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-(2-chlorophenyl)acetamide.
CATO supplies 2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-chlorophenyl)acetamide (CAS 332388-17-7), a certified reference material (molecular formula C22H16BrClN4OS, MW 499.81 g/mol) for analytical method development and quality control.
Structurally, 2-((5-(2-Bromophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-chlorophenyl)acetamide (C22H16BrClN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 499.81 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
