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 research settings to construct pyrazine-based scaffolds that exhibit biological activity. Also utilized in the preparation of labeled compounds for metabolic studies due to the presence of the iodine atom, which can be replaced with radioactive isotopes for imaging or tracing purposes.
