Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective functionalization in heterocyclic chemistry, making it valuable in medicinal chemistry research. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex organic frameworks. Also utilized in radiolabeling studies due to the presence of iodine, enabling imaging and tracer applications in preclinical research.
