Used as a key intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Stille, and Negishi couplings, enabling the construction of complex aromatic and conjugated systems. Its dual halogen functionality (bromo and iodo) allows for selective and sequential substitution due to differing reactivities, making it valuable in the development of organic semiconductors, fluorescent dyes, and liquid crystals. Commonly employed in materials science for synthesizing extended π-conjugated molecules used in OLEDs and organic photovoltaics. Also utilized in pharmaceutical research for building polycyclic frameworks through selective halogen activation.
