Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial drugs due to the quinoline core’s known biological activity. The bromine atom at position 8 allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for building more complex molecules. Also employed in research settings to develop fluorescent probes and sensors, leveraging the inherent fluorescence of the quinoline ring. Its ester group facilitates derivatization or hydrolysis to access carboxylic acid analogs for structure-activity relationship studies.
