可疑检材中二甲基安非他明的确证分析

摘要

对缴获的白色可疑晶体样品进行主要有机成分的检验.采用GC-MS和NMR分析的方法对其进行定性分析.白色可疑晶体样品中的主要有机成分为二甲基安非他明且纯度大于99％.该样品在毒品红外分析时可用作二甲基安非他明的对照品,并成功应用于其他类似案件中检材的定性分析.%N,N-Dimethylamphetamine (DMA) is a methamphetamine (MA) analog and considered as an amphetamine-derived designer drug.In this study,a method of gas chromatography-mass spectrometry (GC-MS) combined with nuclear magnetic resonance spectroscopy (1H and 13C NMR) was developed for the identification of dimethylamphetamine in a suspect exhibit.The results showed that purity of this sample was above 99％ by GC-MS area normalization.Therefore,it could be used as a dimethylamphetamine reference substance in drug FTIR analysis,which was successfully applied to identify samples in other similar cases.
