目的 研究含二硫代羰基的双哌嗪双季铵盐的裂解方式。方法 电喷雾离子阱多级质谱。结果 [M2 + Cl- ] + 碎片呈现双峰 ,[M2 + CH+3 ] + 离子丰度较低 ,同时发现 [M2 + Cl- Cl- PhCH2+ ] + 丰度最高且来源于 [M2 + Cl- ] + ,其碎片裂解机制由多级质谱证明。
Aim To study the cleavage of bis-piperazine double quaternary ammonium salt containing dithiocarbonyl group. Methods Electrospray ion trap multi-stage mass spectrometry. As a result, [M2 + Cl-] + + showed a bimodal peak with lower abundance of [M2 + CH + 3] + ions and the highest abundance of [M2 + Cl- ] +, The fragmentation mechanism of multi-level mass spectrometry proved.
