Used in the synthesis of fluorescent dyes and optical brighteners due to its benzothiazole core, which exhibits strong fluorescence under UV light. Commonly employed in the development of sensors for metal ions, especially zinc and copper, in environmental and biological samples. Also serves as an intermediate in pharmaceuticals, particularly in compounds targeting neurodegenerative diseases. Its amine functionality allows for easy modification in drug design to improve solubility and bioavailability. Found in some agrochemical formulations as a building block for fungicides and plant growth regulators.
