Differentiating methamphetamine samples produced from ephedrine and pseudoephedrine from phenyl-2-propanone precursors is critical for assigning synthetic route information for methamphetamine profiling. The use of isotope ratio mass spectrometry data is now a key component for tracking precursor information. Recent carbon (δ(13)C) isotope results from the analysis of numerous methamphetamine samples show clear differentiation for ephedrine and pseudoephedrine-produced samples compared to P2P-produced samples. The carbon isotope differences were confirmed from synthetic route precursor studies.
区分由麻黄碱和伪麻黄碱制成的甲基苯丙胺样品与由苯-2-丙酮前体制成的样品，对于确定甲基苯丙胺剖析的合成路线信息至关重要。使用同位素比率质谱数据现在是追踪前体信息的关键组成部分。最近对大量甲基苯丙胺样品分析得到的碳（δ(13)C）同位素结果表明，与由苯-2-丙酮制成的样品相比，由麻黄碱和伪麻黄碱制成的样品有明显差异。碳同位素差异已通过合成路线前体研究得到证实。
