Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of biologically active molecules, particularly in pharmaceuticals and agrochemicals. Its reactive bromomethyl group allows for easy alkylation and coupling reactions, making it valuable in constructing complex heterocyclic systems. It is also employed in the development of fluorescent probes and dyes due to the inherent photophysical properties of the benzothiazole core. Additionally, it finds use in medicinal chemistry for synthesizing potential drug candidates targeting neurological disorders and antimicrobial agents.
