Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in the production of fungicides and herbicides due to its reactive halogen sites, which allow for further chemical modifications. Also employed in the development of dyes and fluorescent agents, particularly in applications requiring benzothiazole-based structures. Its brominated structure makes it valuable in cross-coupling reactions, such as Suzuki or Heck reactions, in both research and industrial settings for creating complex organic molecules.
