Characterisation of a proposed internet synthesis of N,N-dimethyltryptamine using liquid chromatography/electrospray ionisation tandem mass spectrometry.

Journal of chromatography. A August 14, 2009 Cláudia P.B. Martins, Sally Freeman, John F. Alder et al. 11 citations

The psychoactive properties of N,N-dimethyltryptamine (DMT) are known to induce altered states of consciousness in humans. These properties attract great interest from clinical, neuroscientific, clandestine and forensic communities. The Breath of Hope Synthesis was reported on an internet website as a convenient two-step methodology for the preparation of DMT. The analytical characterisation of...

Halogenated solvent interactions with N,N-dimethyltryptamine: formation of quaternary ammonium salts and their artificially induced rearrangements during analysis.

Forensic Science International July 4, 2008 Simon D. Brandt, Cláudia P.B. Martins, Sally Freeman et al. 10 citations

The psychoactive properties of N,N-dimethyltryptamine (DMT) 1a are known to induce altered states of consciousness in humans. This particular attribute attracts great interest from a variety of scientific and also clandestine communities. Our recent research has confirmed that DMT reacts with dichloromethane (DCM), either as a result of work-up or storage to give a quaternary N-chloromethyl...

N,N-Dimethyltryptamine and dichloromethane: Rearrangement of quaternary ammonium salt product during GC–EI and CI-MS–MS analysis

Journal of Pharmaceutical and Biomedical Analysis December 28, 2007 Simon D. Brandt, Cláudia P.B. Martins, Sally Freeman et al. 10 citations

N,N-Dimethyltryptamine (DMT) 1 is a simple tryptamine derivative with powerful psychoactive properties. It is abundant in nature and easily accessible through a variety of synthetic routes. Most work-up procedures require the use of organic solvents and halogenated representatives are often employed. DMT was found to be reactive towards dichloromethane, either during work-up or long term...
