Used as an intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of indomethacin and related compounds. Its structure supports the construction of the core aromatic framework required for biological activity in these medications. Commonly employed in pharmaceutical research and development for optimizing reaction pathways and improving yield in active pharmaceutical ingredient (API) synthesis. Also utilized in organic chemistry laboratories for studying ester and amide transformations under various catalytic conditions.
