Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring beta-amino ester functionalities. Its structure supports the construction of more complex molecules in drug discovery, especially in the preparation of analogs for central nervous system agents and cardiovascular drugs. Also employed in the production of agrochemicals and specialty polymers due to its reactive amino and ester groups, enabling coupling reactions and molecular elongation. The hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction conditions.
