Used in pharmaceutical synthesis as a building block for nitrogen-containing heterocyclic compounds. Commonly employed in the development of kinase inhibitors and receptor antagonists due to the pyridine moiety's ability to participate in hydrogen bonding and π-π interactions. Also utilized in the preparation of functionalized ligands for catalysis and in the design of bioactive molecules targeting neurological and inflammatory pathways. Its hydrochloride salt form enhances solubility and stability in aqueous environments, making it suitable for use in polar reaction media and biological assays.
