Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of compounds with biological activity. Its structure serves as a building block in heterocyclic chemistry, enabling the creation of more complex molecules with potential antifungal, antibacterial, or anti-inflammatory properties. Also employed in the preparation of fluorescent dyes and sensors due to the inherent photophysical properties of the benzothiazole core. Its hydroxyl group allows for further functionalization, making it valuable in medicinal chemistry for structure-activity relationship studies.
