NMR: NH2 amino protons. Which solvent could permitted us to show this protons?
« on: June 07, 2011, 08:20:38 AM »
I have a molecule with an amino group and I would like to see this protons. I know that the exchange protons of amino group with water its so fast and it doesnt permit us to show any signal.

What about DMSO? CH2Cl2?....any suggestion...

DMSO followed by a spectrum with the sample shaken with D2O
