摘要
采用红外光谱法和气相色谱-质谱法对两种烷基甲酰吲唑类合成大麻素ADB-4enPINACA和MDMB-4en-PINACA标准品结构进行区分,并对实际烟丝检材中的这两种化合物进行鉴定。结果显示:ADB-4en-PINACA的特征峰位于3354.1,3208.7,682.3 cm^(-1)处,保留时间19.098 min,母离子m/z 342.2,主要子离子m/z 213.1,241.2;MDMB-4en-PINACA的特征峰位于3411.8,1725.4 cm^(-1)处,保留时间13.238 min,母离子m/z 357.2,主要子离子m/z 213.1,270.1。两种化合物产生差异的原因在于ADB-4en-PINACA末端基团为酰胺基,而MDMB-4en-PINACA末端基团为酯基。采用气相色谱-质谱法对疑似含有ADB-4en-PINACA和MDMB-4en-PINACA的样品进行分析,所得质谱特征峰和标准品的基本一致。
The structures of 2 alkylformyl indoles synthetic cannabinoids,ADB-4en-PINACA and MDMB-4en-PINACA,were distinguished by infrared spectrometry and gas chromatography-mass spectrometry,and the 2 compounds in actual tobacco samples were identified.It was shown that the characteristic peaks of ADB-4en-PINACA were located at 3354.1,3208.0,682.3 cm^(-1),with retention time of 19.098 min,parent ion of m/z 342.2,and main daughter ions of m/z 213.1,241.2.The characteristic peaks of MDMB-4en-PINACA were located at 3411.8,1725.4 cm^(-1),with retention time of 13.238 min,parent ion of m/z 357.2,and main daughter ions of m/z 213.1,270.1.The reason for the difference between the 2 compounds was that the terminal group of ADB-4en-PINACA was an amide group,while the terminal group of MDMB-4en-PINACA was an ester group.Gas chromatography-mass spectrometry was applied to analysis of samples suspected to contain ADB-4en-PINACA and MDMB-4en-PINACA,and mass spectrometry characteristic peaks obtained were basically consistent with those of the standards.
