3,4-Methylenedioxymethamphetamine quantification via benchtop 1H qNMR spectroscopy: Method validation and its application to ecstasy tablets collected at music festivals.

Journal of Pharmaceutical and Biomedical Analysis May 30, 2022 Anca Frinculescu, Alexander F G Maier, Trevor Shine et al.

We describe a method validation for the quantification of 3,4-methylenedioxymethamphetamine (MDMA) in tablets based on the United Nations Office on Drugs and Crime (UNODC) guideline for quantitative Nuclear Magnetic Resonance analysis (qNMR). qNMR experiments were carried out on a 60 MHz benchtop NMR spectrometer employing ethylene carbonate as an internal calibrant.
