The study of the fragmentations of the protonated molecular species [M+H] + and selected fragment ions allowed proposals for the main fragmentation pathways of the title compound. In order to better understand the fragmentation pathways, the MS 3 and MS 4 spectra of the title compound were obtained. The main fragmentation pathways occur by the cleavage of the C–CO bonds between N ‐methylpyrrole and carbonyl groups, CO–NH amide bonds, NH–C bonds between the NH groups and the N ‐methylpyrrole rings, and N–C bonds in 1,4,7,10‐tetraazacyclododecane. Electrospray ionization was proven to be a good method for the structural characterization and identification of this kind of compound.
