Chemical Structure
Description
(3AS,6aS)-5-methylene-6a-(naphthalen-2-ylmethyl)hexahydro-1H-cyclopenta[c]furan-1-one (C19H18O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
