CAS :<p>2-(Difluoromethoxy)-5-nitropyridine is a reagent that is used in organic synthesis. This compound is synthesized by the reaction of 2-fluoro-5-nitrobenzaldehyde with difluoromethylmagnesium bromide. The yields for this compound are high and it can be used as a starting material for various chemical reactions, such as formylations, nucleophilic aromatic substitutions, or sulfonylations. The synthesis of 2-(difluoromethoxy)-5-nitropyridine involves an electrophilic substitution at the C2 position of the pyridine ring with the trifluoromethyl group to produce a fluorine atom. The mechanism of this reaction is catalysed by strong bases, such as potassium fluoride.</p>Formule :C6H4F2N2O3Degré de pureté :Min. 95%Masse moléculaire :190.1 g/mol
