Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its multiple halogen atoms allow for selective cross-coupling reactions, making it valuable in the construction of complex aromatic compounds. Commonly employed in Suzuki, Stille, and Ullmann reactions to introduce aromatic frameworks in drug development and materials science. Also utilized in the synthesis of liquid crystals and functional polymers due to its rigid benzene core and reactive halogen sites.
