Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its reactive bromomethyl group allows for easy alkylation and coupling reactions, making it valuable in constructing complex heterocyclic systems. Commonly employed in the development of bioactive molecules, including antimicrobial and antitumor agents. Also utilized in material science for synthesizing functionalized polymers and fluorescent dyes due to the inherent stability and electronic properties of the benzothiazole core.
