Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its halogenated structure allows for selective cross-coupling reactions, making it valuable in constructing complex organic compounds. Commonly employed in the preparation of fluorescent dyes and optoelectronic materials due to the benzo[d]thiazole core's photophysical properties. Also utilized in the manufacture of certain specialty polymers and ligands for catalysis.
