1-Phenyl-2-propanone (P-2-P), also known as benzyl methyl ketone (BMK), is the main precursor used in amphetamine synthesis. In recent years, the number of seizures of P-2-P from both licit and illicit drug manufacture has increased. The present article comprises a discussion of some of the largest

This paper describes the structural elucidation of a compound produced during the synthesis of 3,4-methylenedioxymethylamphetamine (MDMA) via the reductive amination of 3,4-methylenedioxyphenyl-2-propanone (3,4-MDP-2-P) with methylamine and sodium cyanoborohydride. The compound was isolated from

Impurity profiling of seized methamphetamine can provide very useful information in criminal investigations and, specifically, on drug trafficking routes, sources of supply, and relationships between seizures. Particularly important is the identification of "route specific" impurities or those which

The market of pre-precursors and the clandestine production of amphetamine-type stimulants (ATS) has become more and more diverse in recent years. Besides α-phenylacetoacetonitrile (APAAN) and α-phenylacetoacetamide (APAA), glycidic acid derivatives and methyl α-phenylacetoacetate (MAPA) are

During 2000-2001, the Government Laboratory of Hong Kong received over 600,000 ecstasy tablets in more than 2,600 cases. Using GC-MS or FTIR, the major amphetamine-type stimulants were identified, and the samples were categorized into four groups containing: (1) 3,4-methylenedioxymethamphetamine

The headspace profiles of eleven methamphetamine (MA) samples have been analyzed using solid-phase microextraction/gas chromatography-mass spectrometry (SPME/GC-MS). Nine of the eleven are illicit MA seizures from the Southwest U.S. border. One sample is methamphetamine base synthesized in the Drug

We report a case of seized crystalline methamphetamine (MA) samples showing unique drug profiles. The samples were mainly composed of (S)-(+)-MA, with each containing a slight amount of (R)-(-)-MA (enantiomeric excess: 99.2-99.4%). 1-Phenyl-2-propanol and N-methyl-2-phenylacetamide were detected as
