Used in the synthesis of dyes and pharmaceuticals, particularly as an intermediate in the production of local anesthetics like benzocaine and procaine. It also serves in the preparation of UV-absorbing compounds for sunscreens and protective coatings. In research, it acts as a building block for heterocyclic compounds and is employed in the development of sensors due to its amine and carboxylic acid functional groups. Its solubility in water makes it suitable for solution-based reactions and formulations.
