2-Chloro-3-(trifluoromethyl)pyridine is widely used as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs) and agrochemicals due to its reactive halogen and electron-withdrawing trifluoromethyl group. It serves as a precursor for Suzuki-Miyaura and Buchwald-Hartwig couplings to construct complex heterocyclic scaffolds. Researchers also employ it in the development of fluorinated liquid crystals and corrosion inhibitors. Its stability under acidic conditions makes it suitable for multistep synthetic routes.
