Used primarily as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. It is notably employed in the preparation of potent sigma receptor ligands, which are investigated for their potential in treating neurological disorders such as depression, schizophrenia, and neuropathic pain. Additionally, derivatives built from this scaffold have shown promise in improving cognitive function and as potential antipsychotic agents. The hydrochloride salt form enhances solubility and handling during synthetic processes, supporting its use in medicinal chemistry research and development.
