This compound, 4'-Hydroxy-3'-iodo-[1,1'-biphenyl]-4-carbonitrile, is primarily utilized in organic synthesis as an intermediate for developing more complex chemical structures. Its unique structure, featuring hydroxyl, iodo, and carbonitrile functional groups on a biphenyl core, makes it a valuable building block in the synthesis of pharmaceuticals and agrochemicals. The iodo group is particularly useful in cross-coupling reactions, such as Suzuki-Miyaura coupling, for forming carbon-carbon bonds in drug discovery and materials science. The hydroxyl and carbonitrile groups enable further modifications, facilitating the production of compounds with potential biological activity. Additionally, its rigid aromatic framework supports applications in liquid crystals and organic electronic materials.
