Used primarily as a fluorescent whitening agent in textiles and paper to enhance brightness and whiteness under UV light. Also serves as a scintillator in radiation detection devices due to its ability to emit light when exposed to ionizing radiation. Commonly employed in organic light-emitting diodes (OLEDs) as an emissive layer component because of its favorable photophysical properties. Additionally, acts as an intermediate in the synthesis of advanced organic semiconductors and liquid crystal materials.
