Chemical Structure
Description
Structurally, 4-((4-(Ethyl(isopropyl)amino)phenyl)imino)-N-methyl-1-oxo-1,4-dihydronaphthalene-2-carboxamide (C23H25N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 375.46 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).
