Identification of the New Psychoactive Substance Dibutylone.
Objective To establish a method to identify unknown samples based on combined use of gas chromatography-mass spectrometry （GC-MS）, high resolution mass spectrometry （HRMS） and nuclear magnetic resonance spectrum （NMR） technique. Methods The unknown samples were dissolved in methanol solution containing internal standard SKF525A and detected by GC-MS and HRMS. The mixed samples were separated and purified by silica gel column chromatography, and then dissolved in methanol-d4 solution for structural analysis of 新精神活性物质Dibutylone的鉴定. 目的 建立基于气相色谱-质谱（gas chromatography-mass spectrometry，GC-MS）、高分辨质谱和核磁共振波谱技术联合鉴定未知样品的方法。 方法 样品用含内标盐酸双苯戊二氨酯（SKF525A）的甲醇溶液溶解后，采用GC-MS和高分辨质谱检测。混合样品经硅胶柱层析分离纯化后，用氘代甲醇溶液溶解进行核磁共振氢谱（ 法医毒理学；气相色谱-质谱法；高分辨质谱；核磁共振波谱法；1-3，4-（亚甲二氧基）苯基-2-二甲氨基-1-丁酮.
