Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure provides conformational rigidity, making it valuable in medicinal chemistry for enhancing metabolic stability and improving target selectivity. Commonly employed in the design of enzyme inhibitors and receptor modulators, especially within central nervous system (CNS) drug discovery. The amine functionality allows for easy derivatization, enabling rapid exploration of chemical space in structure-activity relationship (SAR) studies. Its hydrochloride salt form improves solubility and handling in aqueous reaction media.
