Used as a key 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, 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 the pyridine moiety into larger drug-like molecules. Also utilized in research settings for the preparation of analogs in structure-activity relationship (SAR) studies.
