Used in pharmaceutical research as an intermediate for synthesizing bioactive compounds, particularly in the development of agents targeting central nervous system disorders. Its structure supports the design of molecules with potential neuroprotective or neuromodulatory effects. Also explored in the synthesis of fluorescent probes due to the presence of the benzo[d]thiazole moiety, which can enhance optical properties for imaging applications. Commonly employed in medicinal chemistry for structure-activity relationship studies involving ester and amide functionalities.
