Used as a fluorescent probe in biochemical and materials science applications due to its strong pyrene-based fluorescence. It is commonly employed in the study of protein interactions, membrane dynamics, and molecular recognition processes. The amine group allows for easy conjugation to biomolecules, polymers, or surfaces, making it valuable in developing sensors, labeling agents, and functional materials. Also utilized in the synthesis of fluorescent dyes and optoelectronic materials because of its excellent photophysical properties.
