alpha-PVP is a potent stimulant of the reuptake inhibitor class. Its similar effects to cocaine, including a mild local anaesthetic effect have lead it to be sold as cocaine, but strangely, also as MDMA. It is class B in the UK and banned in China and many parts of europe.
a-PVP gives no reaction with the marquis reagent, the liebermann reagent and the gallic acid reagent. Alpha-PVP gives a light pink colour with the froehde reagent after 20 seconds.
As always, if you are expecting MDMA and do not get the reaction expected, we recommend disposing of the compound. MDMA does NOT have a numbing effect so you should also discard pills and powders sold as MDMA with a numbing effect.
You can buy the froehde reagent for this test in our store.
