Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in cross-coupling reactions due to the presence of iodine, enabling the formation of carbon-carbon bonds in drug discovery processes. Also utilized in the preparation of fluorinated analogs of bioactive molecules to enhance metabolic stability and binding affinity.
