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 cross-coupling reactions, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Commonly employed in research settings to prepare analogs for structure-activity relationship studies. Also utilized in the preparation of radiolabeled compounds for imaging and tracer studies due to the presence of iodine, which can be substituted with radioactive isotopes like iodine-123 or iodine-131.
