Gas chromatography-mass spectrometry of the N(O)-heptafluorobutyryl isobutyl esters of the protein amino acids using electron impact ionisation
Abstract
The N(O)-heptafluorobutyryl isobutyl esters of the protein amino acids have been analysed by combined gas chromatography-mass spectrometry using electron impact ionisation. The spectral data have been used to confirm the structures of the amino acid derivatives.
