Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of antimalarial and anticancer agents due to its quinoline core and iodine functionality. The iodine atom allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions. Employed in research settings to develop fluorescent probes and sensors owing to the quinoline ring’s photophysical properties. Also investigated for its antimicrobial activity and potential use in medicinal chemistry for targeting DNA in cancer cells.
