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 medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions due to the presence of the iodine moiety, enabling the formation of carbon-carbon bonds in drug discovery pathways. Also utilized in the preparation of biologically active pyrimidine derivatives targeting oncology and central nervous system disorders.
