| Abstract: | Summary. In continuation of our previous work dedicated to the detection of the oxidation products of aminoethylcysteine ketimine
dimer by oxygen reactive species, we give here data for the identification of the α, β unsaturated sulfoxide as the main product of interaction of the dimer with H2O2. Identification has been done on the basis of mass spectrometry and NMR analyses of the product isolated by preparative chromatography.
