Used in the synthesis of biologically active compounds, particularly in pharmaceutical research for developing kinase inhibitors and anticancer agents. Its structure serves as a key intermediate in forming heterocyclic compounds with potential activity against tumor cells. Also employed in the development of fluorescent probes due to the inherent photophysical properties of the benzothiazole core, useful in bioimaging and diagnostic applications. Commonly utilized in cross-coupling reactions to build more complex molecules in medicinal chemistry.
