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.
