〕双派嗪双季铵盐类化合物（Ｍ２＋ ２Ｂｒ－ ２ＨＣｌ）具有良好的抗肿瘤，镇痛和抗氧化作用。本文对三个１，１０－双（Ｎ－取代哌嗪）癸烷双季铵盐新化合物进行了质谱及其裂解规律的研究。从快原子轰击质谱（ＦＡＢＭＳ）得到了［Ｍ＋ Ｘ］＋ 峰，［Ｍ－ Ｈ］＋ 峰和［Ｍ－ Ｒ＋ Ｈ］＋ 峰。此［Ｍ－ Ｈ］＋ 峰可由Ｒ＋ 重排而来。从电子轰击离子化质谱（ＥＩＭＳ）得到了主要碎片峰，特征峰ｍ ／ｚ９９，ｍ ／ｚ１１３，ｍ ／ｚ２８１，ｍ ／ｚ３１１，等也可由类霍夫曼（Ｈｏｆｆｍ ａｎｎ）降解形成。此文为双盐类化合物的质谱研究提供了方法及裂解规律
Bipyrazine double quaternary ammonium compounds (M2 + 2Br-2HCl) has good anti-tumor, analgesic and anti-oxidation. In this paper, three 1,10-bis (N-substituted piperazine) decane bis quaternary ammonium salt of new compounds were studied by mass spectrometry and cleavage. [M + X] + peak, [M- H] + peak and [M- R + H] + peak were obtained from fast atom bombardment mass spectrometry (FABMS). This [M-H] + peak can be rearranged by R +. The major fragment peaks were obtained from electron impact ionization mass spectrometry (EIMS). The characteristic peaks m / z 99, m / z 113, m / z 281, m / z 31 1 and the like can also be formed by Hoffmann degradation. This article provides a method for the study of mass spectrometry of double salt compounds and the rule of cleavage
