The purpose of this study was to determine what variations exist in δ¹³C and δ¹⁵N values of nitrogen sources used in the clandestine production of amphetamine type stimulants (ATS). A survey of previously reported data revealed a lack of information on the novel nitrogen source hydroxylamine. HCl, which can be utilised in the production of MDA from helional. Samples of nitromethane, nitroethane and hydroxylamine.HCl were collected or synthesised for analysis by isotope ratio mass spectrometry (IRMS). Unlike many other nitrogen sources, nitromethane is an uncontrolled substance with legitimate applications. Nitromethane samples were collected from hobby stores around Brisbane, Australia. An investigation into the synthesis of nitromethane.HCl by the acid catalysed hydrolysis of nitromethane is also presented.

The δ¹⁵N values for nitromethane (–37.21 to –0.10‰) and hydroxylamine.HCl (–97.87 to +2.19‰) expand considerably on the previously published δ¹⁵N values of nitrogen sources. The broad range of δ¹⁵N values identified should provide a useful tool in the comparison of ATS, especially when synthesised from the novel precursor helional and utilising hydroxylamine.HCl as a nitrogen source. Relatively consistent δ¹⁵N fractionation was observed for hydroxylamine.HCl synthesised from nitromethane.

本研究的目的是确定δ ¹³ C 和δ ¹⁵存在哪些变化用于秘密生产苯丙胺类兴奋剂 (ATS) 的氮源的 N 值。对先前报告数据的调查显示缺乏有关新型氮源羟胺的信息。HCl，可用于从helional 生产MDA。收集或合成硝基甲烷、硝基乙烷和羟胺.HCl 的样品，用于同位素比质谱 (IRMS) 分析。与许多其他氮源不同，硝基甲烷是一种具有合法用途的不受控制的物质。硝基甲烷样品是从澳大利亚布里斯班附近的业余爱好商店收集的。还介绍了通过硝基甲烷的酸催化水解合成硝基甲烷.HCl 的研究。

的δ ¹⁵为硝基甲烷的N个值（-37.21至-0.10‰）和hydroxylamine.HCl（-97.87至+ 2.19‰）在先前公布的显着扩大δ ^15个的氮源N个值。所确定的大范围δ ¹⁵ N 值应为比较 ATS 提供有用的工具，特别是当从新型前驱体合成并使用羟胺.HCl 作为氮源时。对于从硝基甲烷合成的羟胺.HCl 观察到相对一致的δ ¹⁵ N 分馏。
