Used as an intermediate in pharmaceutical synthesis, particularly in the production of drugs targeting the central nervous system. Its structure supports the development of compounds with activity at receptor sites such as opioid and dopamine receptors. Commonly employed in the preparation of analgesics and psychiatric medications due to its ability to enhance blood-brain barrier penetration. Also utilized in the synthesis of radiolabeled derivatives for receptor binding studies. Its hydrochloride salt form improves stability and solubility in aqueous formulations, making it suitable for use in both research and industrial drug development settings.
