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 degradati

In this work, isomers of 2,4-dimethyl-3,5-bis(3,4-methylenedioxyphenyl)tetrahydrofuran (11) are presented as chemical markers formed during the peracid oxidation of isosafrole. The stereochemical configurations of the major and next most abundant dia
Results presented in this paper demonstrate that time of flight secondary ion mass spectrometry (TOF-SIMS) can be used for the analysis of ballpoint pen inks producing mass spectra that were highly characteristic of the constituent dyes and inorganic

Clandestine synthesis of methamphetamine in Australia has predominantly started from pseudoephedrine extracted from over the counter cold and flu medications. However, recently introduced restrictions on the sale of these products have made pseudoeph

This paper reports the identification of a number of by-products, which are produced during the Wacker oxidation of safrole to 3,4methylenedioxyphenyl-2-propanone (MDP2P) using r-benzoquinone and palladium chloride when methanol is utilised as the so
General synthetic routes to 4-methyl-5-arylpyrimidines and 5-arylpyrimidines are described. 4-Benzylpyrimidine, 4-methyl-5-phenylpyrimidine, 4-(4-methoxybenzyl)pyrimidine, and 4-methyl-5-(4-methoxyphenyl)pyrimidine have been positively identified as

The application of time-of-flight secondary ion mass spectrometry (TOF-SIMS) for the characterisation of gunshot residue (GSR) from 0.22 caliber rimfire ammunition is reported. Results obtained by TOF-SIMS were compared with conventional scanning ele
