4-Bromo-8-methylquinoline

4-Bromo-8-methylquinoline (CAS: 36075-68-0) is a halogenated quinoline derivative used as a key intermediate in the synthesis of bioactive molecules and functional materials. The bromine atom at the 4-position allows it to undergo palladium-catalyzed cross-coupling reactions such as Suzuki, Heck, and Sonogashira, enabling the introduction of various aryl or alkynyl groups. This makes it valuable for the preparation of complex quinoline-based structures used in pharmaceutical research, especially for the development of antimicrobial, anticancer, or antimalarial agents. The methyl group at the 8-position can influence solubility and molecular reactivity, and is useful in designing fluorescent probes, organic semiconductors, or coordination ligands in material science.
