Used as a fluorescent derivatization reagent for chiral amino acids and amines in analytical chemistry. Its high sensitivity allows detection of trace enantiomers in complex mixtures, particularly in HPLC and capillary electrophoresis. The reagent selectively reacts with primary and secondary amines, forming highly fluorescent derivatives that enable precise stereochemical analysis. Widely applied in pharmaceutical quality control to determine enantiomeric purity of drug substances. Also employed in biochemical research for labeling and imaging amine-containing biomolecules with minimal interference due to its distinct excitation and emission wavelengths.
