Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules, particularly in the development of compounds with potential antiviral or anticancer properties. Commonly employed in research settings for constructing complex heterocyclic systems due to the reactivity of the ester group and the fused thiazole ring. Also utilized in the design of fluorescent probes and dyes, where the benzo-thiazole core contributes to light-emitting properties.
