Used as an intermediate in organic synthesis, particularly in the preparation of quinoline-based pharmaceuticals and bioactive compounds. Its functional groups, including the carboxylic acid and N-oxide, enable coordination with metal ions, making it useful in catalysis and the development of metal-organic frameworks. Also employed in research for its potential antimicrobial and antitumor properties due to the quinoline scaffold’s biological activity. The compound's structure supports derivatization for use in medicinal chemistry and drug design.
