Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and anti-inflammatory agents. It serves as a building block in organic reactions where an amino-functionalized aromatic ester is required. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous or polar reaction environments. Also employed in the development of dyes and agrochemicals due to its reactive amine group and ester functionality.
