Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of quinoline-based pharmaceuticals. It serves as a building block in medicinal chemistry for creating compounds with biological activity against Plasmodium species. Also employed in research for developing fluorescent probes due to its conjugated aromatic structure, useful in imaging and detection applications. Additionally, it finds use in the preparation of organic semiconductors and optoelectronic materials because of its electron-accepting properties.
