Used primarily as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of neuroactive compounds. Its spirocyclic structure and nitrogen functionality make it valuable in medicinal chemistry for constructing complex heterocycles. It is employed in research settings to design modulators of central nervous system receptors, including those targeted for treating neurological disorders such as depression, anxiety, and cognitive impairments. The hydrochloride salt form enhances stability and solubility, facilitating its use in solution-phase reactions. Additionally, it serves as a building block in combinatorial chemistry for generating diverse compound libraries aimed at drug discovery.
