Used primarily as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the production of loxoprofen and related profen-class analgesics. Its structure enables efficient coupling in medicinal chemistry pathways, making it valuable in developing anti-inflammatory and pain-relieving agents. The compound’s reactivity and stability under controlled conditions support its use in industrial-scale pharmaceutical manufacturing. It is also employed in research settings for designing novel quinoline-based bioactive molecules with potential therapeutic applications.
