Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and analgesics. Its structure supports the creation of bioactive molecules due to the presence of a chiral center and functional groups amenable to modification. Commonly employed in the preparation of selective receptor agonists and antagonists, especially for neurological targets. Also utilized in research settings for generating compound libraries in drug discovery programs. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction conditions and purification processes.
