Used as a fluorescent whitening agent in textiles and paper to enhance brightness and whiteness by absorbing ultraviolet light and emitting blue light. Also applied in the production of optical brighteners for detergents, improving the visual appearance of washed fabrics. Shows potential in organic light-emitting diodes (OLEDs) due to its luminescent properties. Employed in research as a photoswitchable compound in photochromic materials and molecular switches.
