Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where pyrrolidine derivatives are required. It serves as a chiral building block in the development of drugs targeting central nervous system disorders due to its structural similarity to natural alkaloids. Also employed in the preparation of catalysts for asymmetric synthesis, enhancing the efficiency and selectivity of chemical reactions in drug manufacturing. Its hydrochloride salt form improves stability and solubility, making it suitable for use in aqueous reaction systems.
