Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its bromine functionality allows for further cross-coupling reactions, enabling the introduction of various substituents to modify biological activity. Commonly employed in medicinal chemistry research for constructing quinoline-based derivatives with potential therapeutic effects. Also utilized in the preparation of fluorescent probes due to the inherent photophysical properties of the quinoline core, making it suitable for imaging and sensing applications.
