Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and receptor agonists. It serves as a building block in the preparation of bioactive molecules due to the presence of both amine and pyridine N-oxide functionalities, which can participate in various coupling and reduction reactions. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction conditions. Also employed in the research of nicotinic acetylcholine receptor ligands and in the design of enzyme inhibitors.
