Triphenyl(thiophen-2-ylmethyl)phosphonium bromide (C23H20PSBr) contains sulfur-containing functionality, organophosphorus functionality, bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
