Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and related pharmaceuticals. Its structure supports the development of compounds with analgesic and antipyretic properties. Commonly employed in medicinal chemistry for constructing quinoline-based drug candidates targeting enzyme inhibition, particularly in cyclooxygenase (COX) inhibitor research. Also utilized in the preparation of derivatives for biological activity screening in anti-inflammatory and anticancer studies.
