Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of quinoline-based antimalarial drugs. Its functional groups enable selective derivatization for creating biologically active compounds. Also employed in research for designing kinase inhibitors and antimicrobial agents due to the electron-withdrawing nitrile and halogen substituents enhancing binding affinity. Shows potential in materials science for constructing fluorescent probes, leveraging the quinoline scaffold’s photophysical properties.
