Used as a fluorescent whitening agent in detergents and textiles due to its ability to absorb ultraviolet light and emit blue visible light, enhancing the brightness and whiteness of materials. Also employed in the production of optical brighteners for paper and plastics. Serves as a scintillator in radiation detection devices, where it converts high-energy radiation into detectable light signals. Additionally, functions as a building block in organic semiconductors and optoelectronic materials for applications in OLEDs and UV sensors.
