bk-MDMA Crystals: A Research Reference Overview

bk-MDMA, also known as methylone or 3,4-methylenedioxymethcathinone, is a synthetic cathinone that emerged as a significant research chemical in the late 2000s. At Foreverchems, we provide bk-MDMA crystals exclusively as qualified reference materials for laboratory research and forensic analytical applications.

Chemical Profile

bk-MDMA is the beta-keto analogue of MDMA, distinguished by the addition of a ketone group on the phenethylamine side chain. Its IUPAC name is 1-(1,3-benzodioxol-5-yl)-2-(methylamino)-1-propanone, with a molecular formula of C₁₁H₁₃NO₃ and a molecular weight of approximately 207.23 g/mol . The CAS number is 186028-79-5 . The compound contains a chiral center, existing as a racemic mixture of two enantiomers.

Pharmacologically, bk-MDMA acts as a non-selective substrate at serotonin, dopamine, and norepinephrine transporters. Research published in the British Journal of Pharmacology demonstrated that methylone was the most potent compound among tested cathinones in inhibiting both serotonin and dopamine uptake, with IC₅₀ values correlating with its affinity for these transporters . The compound exhibits a pharmacological profile comparable to MDMA but with slightly reduced potency .

Research Context and Legal Status

bk-MDMA emerged on the research chemical market around 2005, initially marketed as “bath salts” or “plant food” under names including “Explosion,” “Ease,” and “MDMCAT” . According to DEA data, forensic laboratories first identified methylone in 2009 with five drug reports. By 2013, reports had increased dramatically to 10,944 before declining following permanent scheduling .

In drug discrimination studies, bk-MDMA fully substitutes for MDMA in rats trained to discriminate MDMA from saline, with approximately half the potency of MDMA (ED₅₀=6.9 µmol/kg vs. 3.5 µmol/kg) . The compound also fully substitutes for amphetamine with similar potency to MDMA .

The World Health Organization’s Expert Committee on Drug Dependence reviewed methylone and concluded that the degree of risk to public health and society associated with its abuse liability is substantial, with no recorded therapeutic applications . The Committee recommended placement in Schedule II of the 1971 Convention, which was implemented by the Commission on Narcotic Drugs in March 2015 .
