Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules, particularly in the development of antimalarial and anticancer agents. Its halogen and methoxy functional groups allow for selective cross-coupling reactions, making it valuable in medicinal chemistry research. Also employed in the synthesis of ligands for catalytic processes and in the creation of fluorescent probes due to the inherent quinoline ring system's optical properties.
