4-Bromo-4′-iodobiphenyl serves as a critical building block in organic synthesis, particularly for constructing extended π-systems through cross-coupling reactions. In materials science, it’s used to develop organic semiconductors and luminescent materials due to its rigid biphenyl core and halogen handles for further functionalization. Pharmaceutical researchers employ this compound as a precursor for drug candidates targeting kinase inhibition and CNS disorders. The differential reactivity of bromo vs. iodo substituents enables sequential functionalization strategies.
