REACTIONS EUTYLONE (bk-EBDB)
Eutylone (also known as bk-EBDB or n-ethylbutylone) is a stimulant in the synthetic cathinones family, since 2019 often missold as MDMA. What makes it unique is that unlike most cathinones eutylone’s reagent testing results can be almost indistinguishable from the results of MDMA – to an unexperienced eye.
KnowYourStuffNZ found eutylone at every event they attended during the 2019/20 festival season and again at 2020/21 New Year’s festivals, where more than half of the samples turned out not to be MDMA. Drug checking NGOs in other countries also detected eutylone, to various degrees.
Eutylone belongs to the category of New Psychoactive Substances (NPS), which means it’s relatively new and the associated health risks are not fully known. Users have reported stimulation and euphoria at doses as low as 35mg, with an avarage dose reported as 60-100mg.
Eutylone can not be identified by smell or looks. It is most commonly available as an off-white powder, but can also come in crystal, rock, capsule and pill forms. This is what makes it tricky – it looks almost the same as street-quality MDMA, but doesn’t produce the expected effect, possibly leading to using more and intense, unpleasant and dangerous hyperstimulation and psychosis.
Eutylone (bk-EBDB) reagent testing results:
|MARQUIS||yellow / faint orange|
|MECKE||reddish / dark brown|
|MANDELIN||yellow / dark brown|
|LIEBERMANN||orange > brown|
|FROEHDE||yellow > black|
|EHRLICH||No color change|
|HOFMANN||No color change|
|ROBADOPE||No pink color change|
|SCOTT||sample turns blue|
|ZIMMERMANN||faint / no reaction|
Note that only Liebermann and Marquis reagents don’t turn dark, making them the best reagents to distinguish eutylone from MDMA. On the other hand Froehde and Simon’s alone could be misinterpreted as MDMA.

Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. To detect all ingredients and estimate potency it’s required to use an additional purity test kit. A positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.

What if the substance has 50% mdma 50% Eutylone, is it possible to detect the Eutylone?

Yes, using the TLC MDMA purity test kit.
