Used as a chiral building block in organic synthesis, particularly in the production of pharmaceuticals. It serves as a precursor for the synthesis of various biologically active compounds, including peptides and peptidomimetics. Its stereochemistry makes it valuable in asymmetric synthesis, aiding in the creation of enantiomerically pure drugs. Additionally, it is employed in research for developing novel therapeutic agents, especially in the fields of neurology and oncology. Its hydrochloride form enhances solubility, making it more suitable for use in aqueous-based reactions and formulations.
