Chemical Structure

(2R,3R,4R,5R)-2-[(4-chlorobenzoyloxy)methyl]-4-fluoro-5-hydroxy-4-methyloxolan-3-yl 4-chlorobenzoate CAS 1294481-80-3 chemical structure

Description

Structurally, (2R,3R,4R,5R)-2-[(4-chlorobenzoyloxy)methyl]-4-fluoro-5-hydroxy-4-methyloxolan-3-yl 4-chlorobenzoate (C20H29Cl2FO6) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 455.35 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
