Methiopropamine (MPA) is an organic compound structurally related to methamphetamine. Originally reported in 1942, the molecule consists of a thiophene group with an alkyl amine substituent at the 2-position.[2] It appeared for public sale in the UK in December 2010 as a "research chemical" or "legal high", recently branded as Blow.[3] It has limited popularity as a recreational stimulant.[4][unreliable source?]
Pharmacology
Methiopropamine functions as a
Methiopropamine has the potential for significant acute toxicity with cardiovascular, gastrointestinal, and psychotic symptoms.[7]
Metabolism
For N-alkyl amphetamines,
Methiopropamine is
Synthesis
There is a four-step synthesis of methiopropamine. It begins with (thiophen-2-yl)magnesium bromide, which is reacted with propylene oxide, yielding 1-(thiophen-2-yl)-2-hydroxypropane which is reacted with phosphorus tribromide, yielding 1-(thiophen-2-yl)-2-bromopropane which is finally reacted with methylamine, yielding 1-(thiophen-2-yl)-2-methylaminopropane.[13]
Legal status
China
As of October 2015 MPA is a controlled substance in China.[14]
Finland
Methiopropamine is illegal in Finland.[citation needed]
Germany
Methiopropamine is explicitly illegal in Germany.
