Used primarily as a specialty intermediate in organic synthesis, particularly in the preparation of complex aromatic compounds and functionalized benzene derivatives. Its multiple halogen atoms allow for selective cross-coupling reactions, making it valuable in pharmaceutical research and materials science for constructing conjugated systems. Commonly employed in Suzuki, Stille, and Ullmann reactions to introduce aromatic frameworks in advanced intermediates. Also utilized in the development of electronic materials and ligands for catalysis due to its rigid structure and reactivity profile.
