Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners due to its naphthalene backbone and reactive functional groups. Its structure allows for easy modification in organic reactions, making it valuable in developing dyes for textiles, paper, and plastics. Also employed in the preparation of specialty chemicals for electronic materials and sensors where luminescent properties are required. Shows potential in research for photovoltaic devices and OLEDs because of its electron-withdrawing nitrile group and conjugated system.
