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 reactive amine group. The iodo substituent allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, enabling the construction of complex molecular structures. Also employed in materials science for designing fluorescent probes and sensors, leveraging its nitrogen-containing heterocyclic framework.
