Used in organic light-emitting diodes (OLEDs) as a blue fluorescent emitter due to its high quantum efficiency and good thermal stability. Also serves as a fluorescent brightening agent in textiles and plastics, enhancing whiteness and brightness under UV light. Commonly employed in scintillation counters for radiation detection, where it effectively converts ionizing radiation into detectable light pulses. Additionally, it acts as a spectroscopic probe in biochemical research for studying protein interactions and conformational changes.
