Chemical Structure
Description
3-(Triphenylphosphonio)propane-1-sulfonate (C21H21O3PS) contains a steroid core, a sulfone group, a phosphonate group, 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).
