Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for further functionalization, making it valuable in medicinal chemistry for building complex aromatic and heterocyclic systems. Commonly employed in research settings to develop analogs with potential analgesic, antipyretic, or anti-inflammatory properties. Also utilized in the preparation of dyes and specialty organic compounds where chlorinated aromatic esters are required.
