1,1'-(5,5'-Diphenyl-3,3',4,4'-tetrahydro-2H,2'H-[3,3'-bipyrazole]-2,2'-diyl)diethanone CAS 27825-09-8 chemical structure

Description

The occurrence of 1,1'-(5,5'-Diphenyl-3,3',4,4'-tetrahydro-2H,2'H-[3,3'-bipyrazole]-2,2'-diyl)diethanone is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1'-(5,5'-Diphenyl-3,3',4,4'-tetrahydro-2H,2'H-[3,3'-bipyrazole]-2,2'-diyl)diethanone (CAS 27825-09-8), molecular formula C22H22N4O2 and molecular weight 374.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1,1'-(5,5'-Diphenyl-3,3',4,4'-tetrahydro-2H,2'H-[3,3'-bipyrazole]-2,2'-diyl)diethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.44 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).
