Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of bioactive molecules that require iodinated aromatic frameworks. Its nitrile and iodine functional groups allow for further chemical transformations, such as cross-coupling reactions, making it valuable in medicinal chemistry for building complex organic structures. Commonly employed in the development of kinase inhibitors and other targeted therapies. Also utilized in the creation of specialty chemicals where halogenated benzonitrile derivatives are needed.
