Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the production of biphenyl-based pharmaceuticals. It serves as a building block for drug candidates targeting inflammation and pain due to its structural similarity to other arylacetic acid derivatives with known biological activity. Its carboxylic acid group allows for easy derivatization into esters, amides, or salts to improve pharmacokinetic properties. Also employed in research settings for developing new compounds with potential therapeutic effects.
