Used in organic synthesis as a key building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of biaryl and heteroaryl structures in pharmaceuticals and agrochemicals. Its boronate ester group facilitates efficient and selective bond formation under mild conditions. Commonly employed in the development of fluorescent materials and optoelectronic compounds due to the inherent electron-accepting properties of the benzothiazole moiety. Also applied in the synthesis of conjugated polymers for organic semiconductors and sensors.
