Used as a key intermediate in the synthesis of high-performance dyes and pigments, particularly for producing reactive dyes that bond covalently with fibers like cotton and rayon. Its naphthyl groups enhance lightfastness and color intensity, making it valuable in textile dyeing. Also employed in the development of optical brighteners for paper and plastics due to its strong UV absorption and fluorescence properties. Additionally, finds use in organic electronics and photoactive materials because of its stable triazine core and extended π-conjugation, supporting applications in photovoltaics and light-emitting devices.
