Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in cross-coupling reactions, such as Suzuki and Heck reactions, to introduce pyridine-based scaffolds into drug candidates. Also utilized in the preparation of radiolabeled compounds for imaging studies due to the presence of iodine, enabling applications in PET imaging and tracer development.
