Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors. Its structure allows for selective coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to introduce the 5-iodopyrimidine moiety, which can undergo further functionalization via cross-coupling reactions such as Suzuki or Heck reactions. This enables the creation of diverse compound libraries for biological screening. Also utilized in the preparation of potential antiviral and anticancer agents due to the pyrimidine core's relevance in bioactive molecules.
