Eutylone (also known as β-keto-1,3-benzodioxolyl-N-ethylbutanamine, bk-EBDB, and N-ethylbutylone) is a stimulant and empathogenic compound developed in the 1960s,[1][2] which is classified as a designer drug.[3] It was first reported to the EMCDDA in 2014 and became widespread internationally in 2019-2020 following bans on the related compound ephylone.[4][5][6][7] It is not a natural, but a synthetic cathinone.[7] In 2021, eutylone was the most common cathinone identified by the Drug Enforcement Administration in the United States.[8]

Legal status[edit]

Sweden's public health agency suggested classifying eutylone as a hazardous substance, on September 25, 2019.[9]

In the United States Eutylone is considered a schedule 1 controlled substance as a positional isomer of Pentylone[10]
