Ephenidine is a dissociative drug with a very simple chemical structure. It is generally said to have similar effects to methoxetamine (MXE) but is legal in most places in the world. The effects last around 6 hours and the dosage is around 70-110 mg.

We couldn’t find any reagent test results for ephenidine so we took our own. Note that this sample has not had its identity verified yet.

The mandelin reagent goes to a dark green colour within about 10 seconds.
The marquis reagent goes to orange fairly quickly, and progresses to a brownish orange over the course of a 60 second test.
The froehde reagent gives a light yellow colour when reacted with ephenidine.
Finally, the libermann reagent goes very quickly to a deep red and then progresses quite quickly into a simlar red with a more brown body.

2C-T-7 is a psychedelic phenethylamine with a long duration. It has not got the same favourable safety profile as other drugs in the class and deaths have resulted from high doses.

Though the mechanism for these deaths was once speculated to be through MAOI activity, the low MAOI activity of “Aleph” and other alpha-methylated thiophenethylamines suggests that this is not the case, as alpha-demethylation and addition of methoxy groups to the 2 and 5 positions on the ring both result in reduced MAOI activity.

Regardless of this, 2C-T-7 is still dangerous even if we don’t quite know why, so being able to identify it is useful!

You can see colour changes from the liebermann reagent testing kit below.

The test initially (and very rapidly) turns a beautiful royal purple. After about 15 seconds it appears that moisture from the air causes an orange colour to develop at the fringes. Over the course of about 5 minutes the sample turns completely orange.

This sample’s identity was confirmed as 2C-T-7 by WEDINOS.

alpha-PVP,  (a-PVP herein) is a potent stimulant which became popular after mephedrone was banned. Its typical dose is around 20mg and it has a natural numbing effect which leads it to be sold as cocaine and occasionally even as MDMA! Because of its high potency it can cause serious issues when sold pure so detecting it is pretty important, and we could not find reference data for the liebermann and froehde reagent test kits.

The froehde reagent did not yield any colour change but did fizz, indicative of the common HCl salt.

The liebermann reagent gave a light yellow colour. It was a bit stronger in reality than in the photo but it was still not a strong reaction. a-PVP does not give a colour change with the marquis reagent.

This sample was tested as being a-PVP by WEDINOS.

Modafinil is a “eugeroic” drug used to promote wakefulness and alertness without causing impairment or change in mood. It is typically sold as in tablet form for sale as a regulated pharmaceutical but counterfeit pills have been sold.

Modafinil is occasionally sold as an enantiomerically pure preparation and is called armodafinil in this case. The difference is the same as amphetamine and dexamphetamine.

Modafinil reacts with the Froehde reagent to give a bright yellow. The crumbs of tablet go an intense orange-red due to the higher concentration.

The Marquis reagent gives a brownish yellow reagent which is less vibrant than that of the Froehde reagent.

Modafinil reacts to go a “Darkening Orange” when exposed to the Liebermann reagent.¹

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.

The use of 2C-E as a psychedelic drug is well established and cases of mistaken identity appear rare but we noticed that there were no reagent test results for it using the froehde reagent online.

2C-E reacts with the froehde reagent to give a bright lime green colour within a few seconds. You can see the image below

Also shown is the reaction of 2C-E with the marquis reagent. The colour is an orange-brown after twenty seconds.

Some more new reagent results with photos – 3-MeO-PCP is an interesting one here, the reaction is very slow compared to many other chemicals. It causes the marquis reagent to go a pleasant royal blue colour over the course of 1-2 minutes. The froehde reagent is less pronounced, but after it finishes fizzing it takes about the same time to turn to a pale orange colour. This sample is unverified and does not match other tester’s reactions so may be contaminated with an impurity.

Images below are taken at 15 seconds and 2 minutes.

U-47700 is a novel synthetic opioid, one of a very small number of non-fentanyl-derived opioids on the market. Testing with the marquis and froehde reagents both gave fizzing with no colour change on a sample of U-47700. You can see the rather uninteresting images below:

 

Note that the marquis reagent is off-clear but this does not represent a change from its starting colour.
