Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its quinoline core structure contributes to biological activity by interacting with enzyme systems in pathogens or tumor cells. Commonly employed in medicinal chemistry research to build more complex molecules with enhanced therapeutic properties. Also utilized in the preparation of fluorescent probes due to the inherent photophysical characteristics of the quinoline scaffold, aiding in cellular imaging and biochemical assays.
