Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig aminations, to introduce the pyridine moiety into target molecules. Also utilized in the preparation of labeled compounds for medicinal chemistry research, including radiolabeled or fluorescent probes for biological studies.
