Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure supports the development of kinase inhibitors and antimicrobial agents. Commonly employed in research for constructing fused heterocyclic systems due to its reactivity at the bromine position, enabling cross-coupling reactions like Suzuki or Heck reactions. Also explored in the design of fluorescent probes and optoelectronic materials owing to the benzo[d]thiazole core’s photophysical properties.
