Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals and bioactive compounds. Its structure supports the development of antimalarial and anticancer agents due to the presence of iodine, which facilitates further functionalization through cross-coupling reactions. Employed in research for metal ion sensing, particularly for detecting aluminum and zinc in biological and environmental samples, owing to its fluorescence properties when complexed with metals. Also explored in materials science for creating organic semiconductors and photoactive components.
