Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require spirocyclic amine structures. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in drug discovery and process chemistry. Commonly employed in the preparation of kinase inhibitors and other bioactive molecules where structural rigidity and nitrogen functionality are critical. Also utilized in the construction of novel heterocyclic compounds for medicinal and agrochemical research.
