  • Title: Chromatographic separation of conformers of substituted asymmetric nitrosamines.
    Author: Iwaoka WT, Hansen T, Hsieh ST, Archer MC.
    Journal: J Chromatogr; 1975 Jan 22; 103(2):349-54. PubMed ID: 234974.
    Abstract:
    The syn and anti conformers of N-nitrosoproline, N-nitrososarcosine and N-nitroso-2-(ethylamino)-ethanol, have been separated by liquid chromatography. These conformers result from hindered rotation about the N-N bond. Separation was achieved using adsorption, reversed-phase, and ion-exchange modes. For the nitroso-amino acids, a shift in the equilibrium conformer concentration was observed with changes in pH.
