Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its halogenated quinoline structure allows for selective cross-coupling reactions, enabling the construction of complex drug molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of reactive bromo and chloro groups that can be selectively modified. Also utilized in the preparation of antimalarial agents and other biologically active heterocycles where the methoxy and halogen substituents enhance target binding and metabolic stability.
