Used as a key intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the development of selective COX-2 inhibitors. Its aldehyde and ester functional groups allow for further chemical modifications, enabling the construction of complex pharmacophores. Commonly employed in medicinal chemistry for structure-activity relationship studies aimed at improving anti-inflammatory potency and reducing gastrointestinal side effects. Also utilized in the preparation of analogs for biological screening in pain and inflammation research.
