Chemical Structure
Description
Structurally, 7,9-Dichloro-5-(4-chlorophenyl)-2-phenyl-5,10b-dihydro-1H-benzo[e]pyrazolo[1,5-c][1,3]oxazine (C22H15Cl3N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 429.73 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).
