Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig aminations, to introduce pyridine-based scaffolds into drug candidates. Also utilized in radiolabeling studies due to the presence of iodine, enabling imaging and biodistribution analysis in preclinical research.
