Cas no 20857-46-9 (3,4-Bis(trifluoromethyl)pyridine)

3,4-Bis(trifluoromethyl)pyridine is a fluorinated pyridine derivative characterized by the presence of two trifluoromethyl groups at the 3- and 4-positions of the pyridine ring. This structural feature enhances its electron-withdrawing properties, making it a valuable intermediate in organic synthesis, particularly in the development of pharmaceuticals, agrochemicals, and specialty materials. The compound exhibits high thermal and chemical stability due to the strong C-F bonds, while its aromatic pyridine core allows for further functionalization. Its unique electronic properties also make it useful in ligand design for catalysis. The compound is typically handled under inert conditions due to its sensitivity to moisture and air.
