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 ester functionality is required, especially in the development of benzocaine derivatives. Its structure allows for easy modification through acylation, alkylation, or diazotization, making it valuable in medicinal chemistry for creating compounds with analgesic and antipyretic properties. Also employed in the preparation of dyes and heterocyclic compounds due to its aromatic amine group and ester moiety.
