Used as a fluorescent probe in biochemical and analytical applications due to its strong fluorescence and sensitivity to environmental changes. Commonly employed in the development of sensors for metal ions, pH, and biomolecules. Acts as a derivatization reagent for amines and amino acids in chromatography to enhance detection sensitivity. Also utilized in the synthesis of fluorescent dyes and labeling agents for imaging in biological systems. Its electron-donating amino group and electron-withdrawing trifluoromethyl group create a push-pull system ideal for fluorescence, making it valuable in material science for designing optoelectronic materials.
