Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its rigid aromatic structure and ability to enhance photostability. Commonly applied in the development of organic light-emitting diodes (OLEDs) and sensors where electron-transport properties are required. Also found in agrochemicals as a stabilizing component to improve environmental resistance. Its bulky tert-butyl group helps prevent unwanted side reactions in complex syntheses, making it valuable in pharmaceutical research for building sterically hindered molecules.
