Used in the synthesis of pharmaceutical intermediates, particularly in antimalarial and anticancer agents due to its quinoline backbone and functionalizable amino and bromo groups. The compound serves as a building block in medicinal chemistry for constructing more complex heterocyclic systems. Its bromine atom allows for cross-coupling reactions, enabling the introduction of various substituents for structure-activity relationship studies. Also employed in the development of fluorescent probes and dyes, leveraging the inherent photophysical properties of the quinoline ring.
