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] It is a longer chain homologue of α-PVP, having an extra carbon on the alkyl side chain, and is a structural isomer of pyrovalerone.[6]


Sweden's public health agency suggested to classify α-PHP as narcotic on June 1, 2015.[7]

As of October 2015 α-PHP is a controlled substance in China.[8]
