Chemical Structure
Description
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 1,3-Diphenyl-3-(phenylsulfonyl)propan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.43 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).
1,3-Diphenyl-3-(phenylsulfonyl)propan-1-one (CAS 300376-97-0), molecular formula C21H18O3S and molecular weight 350.43 g/mol, is a CATO reference standard with documented purity and traceability.
