摘要:

目的 建立基于气相色谱-四极杆飞行时间质谱(gas chromatography-quadrupole time-of-flight mass spectrometry,GC-QTOF-MS)、超高效液相色谱-四极杆/静电场轨道阱高分辨质谱(ultra-high performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry,UPLC-Q/Orbitrap HRMS)和核磁共振(nuclear magnetic resonance,NMR)技术联合鉴定未知样品的方法。 方法 未知样品用甲醇溶解后供GC-QTOF-MS和UPLC-Q/Orbitrap HRMS检测,用氘代甲醇溶解后供NMR检测。 结果 未知物在GC-QTOF-MS中保留时间为9.67 min的组分实测主要特征离子峰有84.080 8、110.999 7、128.107 0(基峰)和138.994 7等,UPLC-Q/Orbitrap HRMS中实测质子化分子离子m/z为268.109 3。对比合成卡西酮类物质2-甲基-1-(4-甲硫基苯基)-2-吗啉基丙-1-酮[2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one,MTMP]的质谱信息和分子结构,推测未知物为MTMP的类似物。经NMR分析确认为新型N-吗啉取代的合成卡西酮类物质,即1-(4-氯苯基)-2-甲基-2-吗啉基丙-1-酮[1-(4-chlorophenyl)-2-methyl-2-morpholinopropan-1-one,CMMP]。 结论 本研究建立的方法可用于CMMP的结构确证。

Abstract:

Objective To establish a method to identify an unknown substance based on the combined use of gas chromatography-quadrupole time-of-flight mass spectrometry (GC-QTOF-MS), ultra-high performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry (UPLC-Q/Orbitrap HRMS)and nuclear magnetic resonance (NMR) techniques. Methods The unknown substance was dissolved in methanol and was detected by GC-QTOF-MS and UPLC-Q/Orbitrap HRMS, and was dissolved in methanol-d4 to be detected by NMR. Results The main characteristics ion peaks of components with retention time of 9.67 min in GC-QTOF-MS measured were 84.080 8, 110.999 7, 128.107 0 (base peak), 138.994 7, etc. The protonated molecular ion peak m/z in UPLC-Q/Orbitrap HRMS was 268.109 3. It was inferred that the unknown substance was an analog of the synthetic cathinone substance 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one (MTMP) by comparing the mass spectrum information and molecular structure of MTMP. NMR analysis confirmed it as a novel N-morpholine substituted synthetic cathinone substance 1-(4-chlorophenyl)-2-methyl-2-morpholinopropan-1-one (CMMP). Conclusion The method established in this study can be used for structural confirmation of CMMP.
