Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its halogen and methoxy functional groups allow selective modifications for building complex drug molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce aromatic amines or other pharmacophores. Also utilized in agrochemical research for designing bioactive molecules with improved stability and target specificity.
