Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners due to its benzothiazole core, which enhances light absorption and emission properties. Employed in the development of organic semiconductors and electroluminescent materials for OLEDs, leveraging its electron-transport characteristics. Acts as a building block in agrochemicals and pharmaceuticals, particularly in compounds targeting enzyme inhibition. Its tert-butyl group improves lipophilicity and stability, making it suitable for bioactive molecule design. Also applied in polymer stabilization to prevent UV degradation in coatings and plastics.
