2,5-Dibromopyridine is an important dihalogenated pyridine synthetic building block. It owns two reactive bromine atoms at different positions on the pyridine ring, allowing selective stepwise cross-coupling reactions. It can be applied in Suzuki, Heck, Sonogashira and Buchwald-Hartwig amination reactions for molecular modification. It is widely used as key intermediate in the synthesis of kinase inhibitors, anticancer drugs, anti-inflammatory agents and central nervous system therapeutic molecules. Also used for medicinal chemistry compound library construction and structure-activity relationship research, as well as agrochemical and fine chemical synthesis.
