Used in the synthesis of pharmaceutical intermediates, particularly in the production of anti-inflammatory and analgesic drugs. It serves as a building block in organic synthesis due to the presence of both hydroxyl and carboxylic acid functional groups, enabling esterification and ether formation. Also employed in the development of UV-absorbing compounds for use in sunscreens and cosmetic formulations. Its phenolic structure allows for antioxidant applications in specialized industrial formulations.
