preferentially as the dianion ([M – 2H]2–) with a small contribution of the monoanion ([M – H]−). Product ion spectra generated from the [M – 2H]2– precursor ions were dominated by the loss of HSO4– to generate two product ions, that is, the ion at m/z 97 (HSO4–) and the ion corresponding to the remaining monosulfate fragment. Other product ions were found to be specific for some structures. As an example, the
