1H and 31P benchtop NMR of liquids and solids used in and/or produced during the manufacture of methamphetamine by the HI reduction of pseudoephedrine/ephedrine

The synthesis of methamphetamine from pseudoephedrine/ephedrine using hydriodic acid (HI) either directly or in situ is well documented [1 –4]. The manufacture of methamphetamine in New Zealand is almost exclusively carried out via this method, where HI is produced in situ, using iodine and either hypophosphorous acid, phosphorous acid or red phosphorus and water.
