Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong light-emitting properties. Commonly applied in the production of OLEDs (organic light-emitting diodes) for display technologies, where it contributes to efficient blue emission. Also utilized in the development of sensors and bioimaging agents because of its favorable fluorescence characteristics in solid and solution states. Its structural stability and electron-donating ability make it suitable for use in photovoltaic materials and other optoelectronic devices.
