Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with central nervous system activity. Its spirocyclic structure and amine functionality make it valuable in medicinal chemistry for constructing complex amines and heterocycles. The compound is also employed in the preparation of specialty chemicals where a rigid, sterically defined scaffold is needed to influence potency, selectivity, or metabolic stability in drug candidates. Its hydrochloride salt form enhances solubility and handling in aqueous reaction systems.
