Used as a key intermediate in the synthesis of fluorescent brightening agents and optical whitening additives for plastics, textiles, and paper. Its conjugated structure enables strong UV absorption and blue light emission, enhancing the visual brightness and whiteness of materials. Also employed in organic light-emitting diodes (OLEDs) as a blue emitter or host material due to its favorable photoluminescence properties. Additionally, utilized in research for organic photovoltaics and optical sensors owing to its selective light absorption and high thermal stability. Suitable for use in specialty dyes and pigments where high stability and color purity are required.
