Application

5-Fluoro-2-methoxypyridine is widely used as a key intermediate in the synthesis of fluorinated heterocycles for drug discovery, particularly in kinase inhibitors and CNS-targeting compounds. Its electron-deficient pyridine ring facilitates palladium-catalyzed coupling reactions, such as Suzuki-Miyaura and Buchwald-Hartwig transformations. Researchers also employ it in the development of agrochemicals and advanced materials due to its stability and regioselectivity.
