Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure allows for selective binding in asymmetric synthesis, making it valuable in the production of enantiomerically pure drugs, especially in central nervous system agents and anti-inflammatory compounds. The hydrochloride salt form enhances stability and solubility, facilitating handling and downstream processing in drug manufacturing.
