Used as a key intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) requiring spirocyclic amine scaffolds. Its rigid structure and functional group compatibility make it valuable in creating potent bioactive molecules, including central nervous system agents and receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to influence metabolic stability and binding affinity. Also utilized in the preparation of specialty polymers and ligands for catalysis where nitrogen-oxygen heterocycles enhance coordination properties.
