Notes:
The mass spectra of a series of N-phthaloyl and N-trifluoroacetyl derivatives of ω-amino acids ranging from 3-aminopropionic acid to 6-aminohexanoic acid were determined. Ions of significant intensity resulting from the loss of neutral fragments from precursor ions were observed. Deuterium labeling studies indicate the initial fragmentation loss of a neutral molecule; i.e. the loss of water from the molecular ion involves ω-hydrogen loss from the alkyl chain. A fragmentation scheme consistent with metastable, high resolution and deuterium labeling data is presented.
