2-Bromoiodobenzene is primarily utilized in organic synthesis as a versatile intermediate for constructing complex molecules. It is commonly employed in cross-coupling reactions, such as Suzuki and Sonogashira couplings, to form carbon-carbon bonds, which are essential in the production of pharmaceuticals, agrochemicals, and advanced materials. Its dual halogen functionality allows for selective reactivity, enabling chemists to introduce specific structural motifs into target compounds. Additionally, it serves as a precursor in the synthesis of heterocyclic compounds and functionalized aromatic systems, which are valuable in drug discovery and material science. Its stability and reactivity make it a useful reagent in both academic research and industrial applications.
