Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its structure supports the formation of quinoline-based bioactive molecules, which are known for their interaction with biological targets such as enzymes and receptors. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to enhance drug potency and selectivity. Also utilized in the preparation of fluorescent probes due to the inherent photophysical properties of the quinoline scaffold.
