Abstract
Key precursors and by-products in the Leuckardt, Nagai and dissolving metal reductive syntheses of methylamphetamine undergo degradation in soil as a result of biotic and abiotic processes. Furthermore, methylamphetamine is a product of the degradation of 1-(1′,4′-cyclohexadienyl)-2-methylaminopropane and N-formylmethylamphetamine.
These findings have implications for the forensic assessment of buried residues recovered from clandestine laboratory sites because markers used to infer the synthetic methods used might be absent as a result of degradation and because methylamphetamine might be present in residues as a result of degradation rather than as a direct result of its manufacture in the laboratory.
