Chemical Structure
Description
Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (4R)-2-[2-(Diphenylphosphino)-1,1-dimethylethyl]-4,5-dihydro-4-(1-methylethyl)oxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.45 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).
