N-Ethylhexedrone (also known as α-ethylaminocaprophenone, N-ethylnorhexedrone, hexen, and NEH) is a stimulant of the cathinone class[1][2] that acts as a norepinephrine–dopamine reuptake inhibitor (NDRI) with IC50 values of 0.0978 and 0.0467 μM, respectively.[3] N-Ethylhexedrone was first mentioned in a series of patents by Boehringer Ingelheim in the 1960s[4] which led to the development of the better-known drug methylenedioxypyrovalerone (MDPV).[5][failed verification] Since the mid-2010s, N-ethylhexedrone has been sold online as a designer drug.[6][7][8] In 2018, N-ethylhexedrone was the second most common drug of the cathinone class to be identified in Drug Enforcement Administration seizures.[9]

Legal status[edit]

In the United States, N-ethylhexedrone is a Schedule I Controlled Substance.[10] N-Ethylhexedrone is illegal in Japan,[11] and is listed as a potentially harmful substance, but not banned in Sweden.[12][13] In December of 2019, the UNODC announced scheduling recommendations placing N-ethylhexedrone into Schedule II controlled chemical substance alongside other several research chemicals.[14]
