6-Bromo-2,4-dichloroquinoline is a halogenated quinoline derivative. It is a solid compound with a molecular formula of C9H4BrCl2N and a molecular weight of 277.95 g/mol. This molecule features a quinoline core substituted with bromine at the 6-position and chlorine atoms at the 2- and 4-positions, making it a versatile and reactive synthetic building block. Its primary application is as a key pharmaceutical intermediate in medicinal chemistry research and drug development. The presence of multiple halogen atoms at distinct positions on the quinoline scaffold allows for selective functionalization via cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) or nucleophilic aromatic substitution. This makes it a valuable precursor for synthesizing more complex quinoline-based compounds with potential biological activity. As a multi-halogenated heterocycle, it is widely used in constructing libraries of drug-like molecules for screening against various biological targets. It is commercially available from suppliers specializing in advanced intermediates for pharmaceutical R&D. Standard safety precautions for handling halogenated aromatic compounds should be observed.
