Aim To analyze the fragmentation patterns of diquaternary dipiperaziniums containing dithiocarboxyl groups.Methods Positive ion electrospray ionization mass spectrometry in conjunction with tandem mass spectrometry (ESI-MSn) was used.Results The fragment ion [M2+Cl-]+ showed characteristic double peaks with high intensity instead of the parent molecular ion being detected.And [M2+-CH+3]+ ion had relatively low intensity.Meanwhile, [M2+Cl--Cl--PhCH+2]+ species had the highest intensity as the base peak, which was originated from [M2+Cl-]+.The detailed fragmentation mechanisms are supported with the tandem mass spectrometry.
