Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure allows for further functionalization, making it valuable in the development of drug candidates targeting inflammation, microbial infections, and central nervous system disorders. Commonly employed in medicinal chemistry for constructing benzothiazole-based molecules with potential therapeutic properties. Also utilized in research settings to prepare fluorescent probes and dyes due to the inherent photophysical characteristics of the benzothiazole core.
