Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain analgesics and anti-inflammatory agents. It serves as a building block for constructing more complex organic molecules due to the presence of both amino and ester functional groups. Commonly employed in research settings for developing new drug candidates and in the preparation of chiral compounds for asymmetric synthesis. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in various reaction conditions.
