Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its structure serves as a key building block in medicinal chemistry for creating compounds with potential antitumor, antimicrobial, and anti-inflammatory activities. Also employed in the preparation of fluorescent dyes and optoelectronic materials due to the inherent electronic properties of the benzothiazole core. Commonly utilized in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds in complex molecule assembly.
