Used as a key intermediate in the synthesis of fluorogenic labeling reagents for amino acid analysis, particularly in the development of high-sensitivity detection methods in chromatography. Its structure allows selective derivatization of primary amines, enabling the detection of trace amounts of biomolecules in biological samples. Also employed in the preparation of fluorescent probes for imaging and biochemical assays due to its strong emission properties when conjugated. Shows utility in medicinal chemistry for constructing nitrogen-containing heterocyclic compounds with potential biological activity.
