3-Bromoquinoline

3-Bromoquinoline (CAS 5332-24-1) is a strategically functionalized fused bicyclic heterocyclic scaffold engineered for cross-coupling reactions, pharmaceutical intermediate development, and materials science applications. This molecule integrates a quinoline core—a fused benzene-pyridine bicyclic system prevalent in bioactive natural products and pharmaceuticals (including antimalarial drugs like quinine and chloroquine)—with a bromine substituent at the C3 position. The C3-bromo handle serves as a privileged site for Pd-catalyzed cross-coupling (Suzuki, Stille, Negishi, Sonogashira), enabling efficient introduction of diverse aryl, alkyl, or heteroaryl groups to the quinoline scaffold. The fused bicyclic architecture provides enhanced rigidity, extended π-conjugation, and improved metabolic stability compared to monocyclic pyridine analogs, making it particularly valuable for constructing kinase inhibitor cores, antimalarial agents, antimicrobial compounds, and functional materials where the quinoline motif offers superior target binding affinity and photophysical properties. Compared to halogenated pyridines, quinoline derivatives provide expanded aromatic surface area for π-stacking interactions and distinct electronic distribution across the fused ring system. Manufactured with purity ≥98% under controlled conditions, it supports drug discovery and materials science programs requiring modular access to functionalized quinoline architectures.
