Chemical Structure
Description
(1S,4aS,10aR)-1-(Hydroxymethyl)-7-isopropyl-8-methoxy-1,4a-dimethyl-1,4,4a,9,10,10a-hexahydrophenanthren-2(3H)-one (C21H30O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
