Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. It serves as a building block in organic reactions where selective halogen substitution is required, due to the differing reactivity of bromo and chloro groups. Commonly employed in cross-coupling reactions such as Suzuki or Ullmann reactions to construct carbon-carbon or carbon-heteroatom bonds. Also utilized in the development of specialty chemicals including dyes and functional materials where controlled substitution patterns are essential.
