Chemical Structure

(8S,9S,10R,13S,14S)-13-ethyl-11-methylidenespiro[1,2,4,7,8,9,10,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthrene-3,2'-1,3-dioxolane]-17-ol CAS 1574323-08-2 chemical structure

Description

Structurally, (8S,9S,10R,13S,14S)-13-ethyl-11-methylidenespiro[1,2,4,7,8,9,10,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthrene-3,2'-1,3-dioxolane]-17-ol (C22H32O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 344.49 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).
