β-Keto-1,3-benzodioxolyl-N-ethylbutanamine (Eutylone, bk-EBDB, N-Ethylbutylone) is a stimulant and empathogenic compound developed in the 1960s,[1] which has been reported as a novel designer drug,[2] first being reported to the EMCDDA in 2014 but becoming widespread internationally in 2019-2020 following bans on the related compound ephylone.[3][4][5]

Legal status[edit]

Sweden's public health agency suggested classifying Eutylone as a hazardous substance, on September 25, 2019.[6]
