Notes:
The components of mixtures of dipeptides can be identified from the electron ionization and chemical ionization mass spectra of their N-acetylacetonyl methyl ester derivatives without prior separation. The pyrolytic conversion of peptide trimethylanilinium salts to their methyl esters in the direct insertion probe of a mass spectrometer was found to be most suitable for the derivatization of dipeptides in mixtures.
