Used as a fluorescent derivatization reagent for the detection and analysis of amino acids and primary amines in biological samples. Its high sensitivity in fluorescence detection makes it valuable in HPLC and capillary electrophoresis methods, particularly in clinical and biochemical research for profiling amino acids in urine, plasma, and tissues. Also employed in the synthesis of pharmaceutical intermediates and coordination chemistry as a ligand due to its nitrogen-containing heterocyclic structure.
