Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of vasodilator drugs and organic nitrogen-containing compounds. It serves as a protecting group reagent for carbonyl and amine functionalities during multi-step syntheses due to its selective reactivity. Also employed in the development of agrochemicals and functional materials where controlled release of nitrogen or oxygen functionalities is required. Its hydrochloride salt form enhances stability and solubility in polar solvents, making it suitable for use in aqueous and mixed solvent systems.
