CAS:2-Chloro-6-(chloromethyl)pyridine (2C6CP) is a chloride precursor that can be used for the synthesis of metal chlorides, such as copper chlorides. 2C6CP is synthesized by reacting thionyl chloride with the substituted pyridine under anhydrous conditions at -78°C. The resultant 2C6CP is then hydrolyzed to produce the desired chloride.
2C6CP has been shown to act as a ligand in coordination chemistry. It was first synthesized by reacting 3-chloropyridine with thionyl chloride and then hydrolyzing it to 2-chloropyridine. This method was later modified to use 4-chlorobenzoyl chloride instead of 3-chloropyridine, producing 2,4-dichloropyridine.Fórmula:C6H5Cl2NPureza:Min. 95%Peso molecular:162.02 g/mol2-Methoxy-4-methylpentanoic acid
