Used as a fluorescent probe in biochemical and analytical applications due to its ability to emit light upon excitation. It serves as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in compounds requiring benzothiazole moieties, where benzothiazole derivatives often exhibit antibacterial, antifungal, and anti-inflammatory properties. Employed in corrosion inhibitors for metals in industrial cooling systems. Also utilized in the development of sensors for metal ion detection, especially for zinc and copper in environmental and biological samples. Its derivatives are explored in the design of organic semiconductors and luminescent materials for optoelectronic devices.
