Chemical Structure
Description
5-(((4-Methoxybenzyl)thio)methyl)isoxazol-3(2H)-one (C12H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
