CATO supplies 2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-1-phenylethanone (CAS 738604-79-0), a certified reference material (molecular formula C21H15BrN4OS, MW 451.34 g/mol) for analytical method development and quality control.

Structurally, 2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-1-phenylethanone (C21H15BrN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 451.34 g/mol, it falls into the moderately-high-molecular-weight range. 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).

As a certified reference material (CRM), 2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-1-phenylethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
