7—哌嗪喹诺酮类化合物的质谱研究

Study on Mass Spectrometry of 7-Piperazine Quinolones

本文报导了五种7—哌嗪喹诺酮类化合物的EI谱，并讨论了特征碎片离子的裂解规律。8－N－7—哌嗪喹诺酮化合物的m／z（M－68）可能来自3氢原子的重排的结果。

In this paper EI Mass Spectra of five 7-Piperazing Quinolones were measured. The fragmentations of characteristic fragment ions were discussed. The m/z(M-68) fragment ion of 8-N-7-Piperazine Quinolones probably results from a rearrangement of three hydrogens.
