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 heterocyclic compounds with potential antimicrobial, antifungal, or anti-inflammatory properties. Commonly employed in medicinal chemistry for constructing benzothiazole-based drug candidates. Also utilized in the preparation of fluorescent probes and dyes due to the inherent photophysical properties of the benzothiazole core.
