Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules and functional materials. Its iodine moiety allows for cross-coupling reactions, enabling the construction of complex aromatic systems. Commonly employed in the synthesis of fluorescent dyes, optoelectronic materials, and receptor ligands due to the electron-withdrawing nature and stability of the benzothiazole core. Also explored in medicinal chemistry for designing kinase inhibitors and imaging agents.
