Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of quinoline-based pharmaceuticals. It exhibits biological activity that makes it valuable in medicinal chemistry for designing compounds with antimicrobial and antiparasitic properties. Also employed in research for developing fluorescent probes due to its ability to chelate metal ions and emit detectable signals in sensing applications. Its derivatives are explored in materials science for optoelectronic devices owing to their luminescent characteristics.
