Used in organic synthesis as a building block for pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and amine functionality make it valuable for constructing complex amines and heterocyclic compounds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in projects targeting central nervous system (CNS) agents and enzyme inhibitors. The hydrochloride salt form enhances stability and solubility, facilitating handling and formulation in early-stage drug discovery.
