SDS of cas: 221012-82-4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine, is researched, Molecular C38H34N2O4P2, CAS is 221012-82-4, about 3,3′-Bipyridine, 4,4′-bis(diphenylphosphino)-2,2′,6,6′-tetramethoxy-, (3R)-; 3,3′-Bipyridine, 4,4′-bis(diphenylphosphino)-2,2′,6,6′-tetramethoxy-, (3S)-.
