Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for constructing novel compounds with improved metabolic stability and binding affinity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in the design of enzyme inhibitors and receptor modulators. The amine group allows for easy derivatization, enabling rapid generation of compound libraries for drug discovery.
