Used in the synthesis of pharmaceutical intermediates, particularly in the development of antimalarial and anticancer agents. Its structure serves as a key building block in heterocyclic chemistry, enabling the creation of complex molecules with biological activity. Commonly employed in research settings to design kinase inhibitors and fluorescent probes due to its quinoline core, which enhances binding affinity and cellular uptake. Also utilized in coordination chemistry as a ligand for metal complexes with potential catalytic or medicinal applications.
