Used in the synthesis of pharmaceutical intermediates, particularly in the development of antimalarial drugs. It serves as a building block in organic reactions due to its reactive quinoline ring and ester functionality. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles. Also utilized in research settings for developing fluorescent probes and dyes, leveraging the inherent fluorescence of the quinoline core. Its derivatives are explored for biological activity in antimicrobial and anticancer studies.
