Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports metal chelation, making it useful in coordination chemistry for catalyst design. Also employed in the preparation of fluorescent probes due to its ability to form stable complexes with metal ions, enhancing detection sensitivity in biological imaging. Shows potential in materials science for designing organic semiconductors owing to its conjugated aromatic system and hydrogen-bonding capability.
