alpha-Pyrrolidinohexiophenone

α-Pyrrolidinohexiophenone (α-PHP, alpha-PHP, α-Pyrrolidinohexanophenone, PV-7) is a synthetic stimulant drug of the cathinone class developed in the 1960s[1] which has been reported as a novel designer drug.[2][3][4][5][6]

α-Pyrrolidinohexiophenone is a longer chain homologue of α-PVP, having an extra carbon on the alkyl side chain. Regarding the potency of alpha-PHP in the brain, chemist Michael H. Baumann of the Designer Drug Research Unit (established by Baumann[7]) of the National Institute on Drug Abuse stated: "alpha-PHP might be even more potent than alpha-PVP"; this statement is based on laboratory tests of chemical reactivity.[8]

Pyrovalerone is a structural isomer of alpha-PHP.[9]

Legality

In the United States, α-PHP is a Schedule I Controlled Substance.[10]

The President of the Republic of Italy classified cathinone and all structurally derived analogues (including pyrovalerone analogues) as narcotics on January 2012.[11][12]

Sweden's public health agency suggested to classify α-PHP as narcotic on June 1, 2015.[13]

As of October 2015, α-PHP is a controlled substance in China.[14]

In December 2019, the UNODC announced scheduling recommendations placing Alpha-PHP into Schedule II.[15]
