The major fragments of the precursor ion at m/z 1048
Fragment ions originating from the precursor molecular ion of 1048 were subjected to MS/MS fragmentation as described under “Experimental procedures.” The proposed molecular formulae of the product ions are supported by the observed isotope patterns for the relevant ions.
