Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of 8-aminoquinoline derivatives. It serves as a building block in medicinal chemistry for creating compounds with biological activity against parasitic infections. Also employed in coordination chemistry as a ligand for metal ions, facilitating catalytic reactions and the formation of metal-organic frameworks. Its structure supports chelation, making it useful in designing sensors and fluorescent probes for metal detection in environmental and biological systems.
