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.展开更多
