Chemical Structure
Description
3-(4-Fluorophenyl)-5-(o-tolylamino)thiazolidine-2,4-dione (C16H13FN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-(4-Fluorophenyl)-5-(o-tolylamino)thiazolidine-2,4-dione (CAS 1025499-75-5), molecular formula C16H13FN2O2S and molecular weight 316.35 g/mol, is a CATO reference standard with documented purity and traceability.
