Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of analgesic and anti-inflammatory agents. Its structure allows for incorporation into more complex molecules where the p-tolyl and ester functionalities are needed for biological activity. Commonly employed in medicinal chemistry for building blocks in drug development, especially in routes requiring chiral amino acid derivatives. Also utilized in the preparation of local anesthetics and central nervous system-active compounds due to its amine and aromatic features. The hydrochloride salt form enhances stability and solubility during synthetic processes.
