Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Stille, and Negishi couplings, to construct complex aromatic and conjugated systems. Its dual halogen functionality allows selective reaction control, making it valuable in the preparation of organic semiconductors, fluorescent dyes, and pharmaceuticals. Commonly employed in materials science for developing organic electronic devices like OLEDs and OFETs due to its ability to extend π-conjugation in molecular frameworks.
