ESI-MS of Three Hindered Amine Free Radical Stabilizers

This article briefly described the characteristic mass spectra and structures of three hindered amine free radical stabilizeres. ESI-MS technology is applied on three hindered amine free radical stabilizers. With ESI-MS, not only the quasi-molecular ion peak, but much more fragment information by the further ionization is aquired. So it provides reliable structure information for the samples.
