Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong photoluminescent properties. Its structure supports electron delocalization, making it suitable for applications in organic light-emitting diodes (OLEDs) and sensor technologies. Also employed in the development of fluorescent probes for biological imaging, where it helps detect specific proteins and monitor cellular processes. Additionally, it finds use in agrochemicals as a component in UV-stable formulations.
