Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. It serves as a chiral building block in asymmetric synthesis, enabling the development of enantiomerically pure compounds. Also employed in the preparation of agrochemicals and biologically active molecules due to its amine functionality and structural configuration. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in various reaction conditions.
