Chemical Structure

1-(2,4-Bis(benzyloxy)-5-iodophenyl)ethanone CAS 157953-16-7 chemical structure

Description

Structurally, 1-(2,4-Bis(benzyloxy)-5-iodophenyl)ethanone (C22H19IO3) contains a steroid core, a hydroxyl group, an ether linkage, iodine substitution. 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 458.29 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
