Used in the synthesis of pharmaceutical intermediates, particularly in the development of anti-inflammatory and analgesic drugs. Acts as a building block in organic synthesis due to the presence of both carboxylic acid and hydroxyl functional groups, enabling esterification and amidation reactions. Employed in the preparation of UV-absorbing compounds for use in coatings and polymers. Also utilized in the formulation of certain agrochemicals and dyes, where its aromatic structure contributes to stability and reactivity.
