Used as a fluorescent derivatization reagent for the detection and quantification of primary and secondary amines in analytical chemistry. Its high sensitivity and selectivity make it suitable for labeling amino acids, peptides, and neurotransmitters in high-performance liquid chromatography (HPLC) with fluorescence detection. The compound reacts readily with amine groups under mild conditions, forming highly fluorescent derivatives that are stable and easily detectable at low concentrations. It is also employed in biochemical research for tagging biomolecules in imaging and assay development due to its strong emission properties in the visible range.
