Used as a fluorescent derivatization reagent in analytical chemistry, particularly for the detection and quantification of carbonyl compounds such as aldehydes and ketones. Its high sensitivity to fluorescence enables trace analysis in environmental and biological samples. Also employed in the synthesis of pharmaceuticals and agrochemicals due to its nitrogen-containing heterocyclic structure, which serves as a building block in various drug development processes. Additionally, it acts as a ligand in coordination chemistry for metal ion detection and catalysis.
