Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the development of fenbufen and related analogs. Its structure supports metabolic stability and enhances lipophilicity, improving drug absorption and duration of action. Also employed in research for developing heterocyclic compounds with potential biological activity, including antimicrobial and anticonvulsant agents. Its carboxylic acid functionality allows for easy derivatization, making it valuable in medicinal chemistry for ester and amide formation.
