2,6-二氨基-3,5-二硝基吡嗪标准物质的波谱学研究
Spectroscopy of 2,6-diamino-3,5-dinitropyrazine reference material
【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,13C,15N 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13CNMR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15N的化学位移分别为δ–13.95,δ–139.66,δ–74.43,δ–281.28。
【Abstract】 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 1 H, 13C and 15N NMR technology. The results showed that ANPZ molecule was in accordance with the predicted structure, 1 H NMR showed two single peaks at δ 8.62 and δ 8.23 which were assigned to amino group hydrogen, 13C NMR chemical shifts at δ 151.2 and δ 125.6 were assigned to the carbon atom attached to amino group and the carbon atom attached to nitro group, and 15N chemical shifts at δ –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.
