Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and antimicrobial agents. Its quinoline-based structure supports the creation of complex heterocyclic compounds that exhibit biological activity. Also employed in research for developing fluorescent probes due to its ability to form coordination complexes with metal ions. Shows potential in materials science for designing organic semiconductors and optoelectronic devices. Additionally, used as a reagent in organic reactions to create derivatives with special properties for scientific studies.
