Structurally, 3-{[3-(benzyloxy)-4-methoxyphenyl]methylidene}-9-oxo-1h,2h,3h,9h-pyrrolo[2,1-b]quinazoline-6-carboxylic acid (C27H22N2O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 454.47 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).
