Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the development of COX-2 inhibitors. Its structure supports the design of compounds with selective enzyme inhibition, improving therapeutic efficacy and reducing side effects. Also employed in research for developing bioactive molecules with antioxidant and antimicrobial properties. Its phenolic and carboxylic functional groups allow easy modification for pharmaceutical and medicinal chemistry applications.
