Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive bromomethyl group allows for easy alkylation, making it valuable in constructing more complex benzothiazole derivatives. Commonly employed in the development of bioactive molecules, including antimicrobial and antifungal agents. Also utilized in the preparation of fluorescent dyes and optical brighteners due to the inherent fluorescence of the benzothiazole core. Plays a role in coordination chemistry as a ligand precursor in metal-organic frameworks and catalysts.
