Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocycles found in bioactive molecules. Commonly employed in medicinal chemistry for modifying core scaffolds to enhance potency, selectivity, and metabolic stability. Also utilized in cross-coupling reactions due to the presence of the iodine moiety, enabling carbon-carbon bond formation in complex molecule assembly.
