is provided while some fragmentation remains to elucidate structural details. Subsequently, in three urine samples obtained from different and unrelated MDMA intoxications, the enantiomers of MDMA and MDA were identified. In some urine samples also HMMA and/or HMA were found. In addition to these compounds, an unexpected compound and/or additional chiral metabolite, N-hydroxy-(RS)-3,4-methylenedioxyamphetamine
获得了定性的GC / MS谱图,并表征了其质谱特征,用于分析(RS)-3,4-亚甲二氧基甲基苯丙胺(MDMA)及其代谢物(RS)-3,4-亚甲二氧基苯丙胺(MDA)的对映体,( RS)-4-羟基-3-甲氧基甲基苯丙胺(HMMA)和(RS)-4-羟基-3-甲氧基甲基苯丙胺(HMA)。选择一种手性衍生化方法,以获得用非手性GC固定相分离各个对映异构体所需的非对映异构体。选定的衍生化反应包括与N-七氟丁酰基-(S)-脯氨酰氯的反应以及与N-甲基-N-三甲基甲硅烷基三氟乙酰胺的连续反应,得到N- [七氟丁酰基-(S)-脯氨酰基] -O-三甲基甲硅烷基的衍生物。用电子电离和正化学电离(PCI)离子阱质谱进行检测。通过PCI获得的目标化合物的参考标准品的衍生物的质谱图表明,该方法可同时在离子阱中引发质子和电荷转移反应。优点是在提供大量信息的同时保留了一些碎片以阐明结构细节。随后,在从不同且无关的MDM
