Synthesis and analytical characterization of monomeric N-oxidized derivatives of α-tocopheramine

Abstractα-Tocopheramine has shown great promises as a stabilizer for synthetic and natural polymers, but is also investigated in various biomedical scenarios. Many studies have been hampered by the fact that the oxidation products of α-tocopheramine have not yet been properly identified and their analytical data are still lacking. In the present study, we synthesized and fully analytically characterized all N-oxidation products that can form upon oxidation of α-tocopheramine in aqueous media, including the hydroxylamine, nitroso, and nitro derivative, in this way providing standards for the identification of the so far elusive byproducts. Synthesis and stability of the derivatives are discussed. Graphic abstract
