Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure allows for functionalization at multiple sites, making it valuable in the development of heterocyclic compounds with potential antimicrobial, antifungal, or anti-inflammatory properties. Commonly employed in coupling reactions to form amides or esters for drug discovery research. Also utilized in the preparation of fluorescent probes and dyes due to the benzo[d]thiazole core, which exhibits favorable photophysical properties.
