Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its rigid aromatic structure and electron-withdrawing nitrile group. Its derivatives are found in agrochemicals, particularly as fungicides and plant growth regulators. Also employed in the development of pharmaceuticals, especially in compounds targeting central nervous system disorders and inflammation. Shows potential in material science for organic semiconductors and sensors because of its ability to form stable charge-transfer complexes. Commonly utilized in research for constructing benzothiazole-based heterocycles with bioactive properties.
