Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in the production of certain fungicides and herbicides due to its stable heterocyclic structure and reactive bromine sites. The compound is also employed in the development of dyes and fluorescent whiteners for textiles, where it contributes to light stability and color fastness. In research, it acts as a reagent for creating complex benzothiazole derivatives with potential biological activity, including antimicrobial and antitumor properties. Its selective reactivity makes it valuable in cross-coupling reactions for forming carbon-heteroatom bonds in advanced organic synthesis.
