Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure supports the development of sulfur-containing heterocyclic systems, which are important in drug design for their antimicrobial, antifungal, and antitumor properties. Commonly employed in the preparation of fluorescent dyes and sensors due to the benzo[d]thiazole core’s photophysical characteristics. Also utilized in coordination chemistry as a ligand for metal ions in catalytic applications.
