摘 要:制备了2,6-二氨基-3,5-二硝基吡嗪(ANPZ)纯度标准物质,采用红外(IR)、质谱(MS)、核磁共振(NMR)技术对其进行了结构表征。并使用~1H,^(13)C,^(15)N NMR技术,对其全部NMR信号进行了归属。结果表明,ANPZ分子与预测结构一致,其氨基偕位氢在~1H NMR中表现为2个单峰,化学位移分别为δ8.62,δ8.23;氨基碳、硝基碳的^(13)CNMR化学位移分别为δ151.2,δ125.6;硝基、吡嗪环1位氮、吡嗪环4位氮、氨基的^(15)N的化学位移分别为δ–13.95,δ–139.66,δ–74.43,δ–281.28。The purity reference material of 2,6-diamino-3,5-dinitropyrazine(ANPZ)was prepared,and its structure was characterized by infrared spectrum(IR),mass spectrometry(MS)and nuclear magnetic resonance(NMR).All NMR signals were assigned by 1H,13C and 15N NMR technology.The results showed that ANPZ molecule was in accordance with the predicted structure,1H NMR showed two single peaks atδ8.62 andδ8.23 which were assigned to amino group hydrogen,13C NMR chemical shifts atδ151.2 andδ125.6 were assigned to the carbon atom attached to amino group and the carbon atom attached to nitro group,and 15N chemical shifts atδ–13.95,δ–139.66,δ–74.43,δ–281.28 were assigned to the nitrogen atoms of nitro,N1 in pyrazine ring,N4 in pyrazine ring and amino respectively.
