Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) drugs. Its structure supports the formation of bioactive molecules with potential antipsychotic, antidepressant, or cognitive-enhancing effects. The presence of both hydroxyl and chloro functional groups allows for selective modifications, enabling chemists to tailor molecular properties for improved efficacy and metabolic stability. It is also explored in the preparation of enzyme inhibitors and receptor modulators due to its conformationally constrained piperidinone core.
