Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Ullmann reactions, to construct complex aromatic and heteroaromatic systems. Its dual halogen functionality allows selective sequential coupling, making it valuable in the development of functional materials like organic semiconductors, liquid crystals, and pharmaceuticals. Commonly employed in the synthesis of polyaromatic frameworks for use in optoelectronic devices, including OLEDs and organic field-effect transistors (OFETs).
