Application

3-Bromo-5-chloro-2-methoxypyridine serves as a key building block in medicinal chemistry for the synthesis of kinase inhibitors and antiviral agents. Its halogenated pyridine core is utilized in Suzuki-Miyaura and Buchwald-Hartwig couplings to construct complex bioactive molecules. Researchers also employ it in the development of agrochemicals, such as herbicides and fungicides, due to its reactive halogen sites. The methoxy group enhances solubility and directs further functionalization in metal-catalyzed reactions.
