The fragmentation of a series of N-carboxymethyl-N-substituted carbamoylmethyl-2,3-dialkoxy-5-carbalkoxybenzylamine, a new type of chelating agent against uranium intoxication, was studied using Fast-atom bombardment mass spectrometry. The site of chelation with iron was proposed on the basis of these experiments
