Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its bromo and ketone functional groups allow for further chemical modifications, enabling the creation of complex heterocyclic compounds. Commonly employed in medicinal chemistry research for structure-activity relationship studies. Also utilized in the preparation of fluorescent probes due to the inherent photophysical properties of the quinoline scaffold, making it suitable for bioimaging and sensor applications.
