Used as a key intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and nitrogen atoms make it valuable for constructing complex heterocyclic compounds with potential activity in central nervous system therapies. It is also employed in the preparation of kinase inhibitors and receptor modulators due to its ability to enhance binding selectivity and metabolic stability in medicinal chemistry. Additionally, it serves as a building block in the design of novel compounds for research in oncology and neurodegenerative diseases.
