Chemical Structure
Description
Structurally, 4,4,5,5-Tetramethyl-2-(4-methylnaphthalen-1-yl)-1,3,2-dioxaborolane (C17H21BO2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 268.16 g/mol, it falls into the medium-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.
