α-PHP ( α-Pyrrolidinohexiophenone , alpha-PHP, α-Pyrrolidinohexanophenone, PV-7) is a synthetic stimulant drug of the cathinone class developed in the 1960s which has been reported as a novel designer drug. 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.
alpha-Pyrrolidinohexiophenone (also known as PV-7, alpha-PHP, A-PHP, and α-PHP) is a popular synthetic stimulant of the cathinoneand pyrrolidine chemical classes that produces typical short-lived substituted cathinone effects such as euphoria, thought acceleration, disinhibition and ego inflation when administered.It is structurally related to compounds such as MDPV and is one of the successors to the designer drug cathinone analog α-PVP.
α-PHP generally comes in the form of either a fine powder or crystallized shards which users can ingest to produce powerful but short-lived euphoric stimulant effects which are comparable to those of methamphetamine and cocaine when insufflated or vaporized. Like its research chemical cathinone predecessors, it is has gained notoriety for its tendency to induce compulsive redosing and addictive behaviors in a large percentage of its users as well the ability to readily induce delusional states and psychosis when abused
α-PHP has a short history of use and is subject to much scrutiny by the media. It is being used and marketed as a replacement for α-PVP (known on the street as flakka) a few years following its ban, where it has come to substitute α-PVP in many parts of the world. While initially mass synthesized in Chinese industrial laboratories, a ban on α-PHP within China’s borders has forced production to nations worldwide.
Very little data exists about the pharmacological properties, metabolism, and toxicity of α-PHP. It has recently become commonly marketed alongside research chemical stimulants like NEP and Hexen as a legal, grey-market alternative to a-PVP, and commercially distributed through online research chemical vendors.
α-PHP, or α-Pyrrolidinohexanophenone, is a compound of the substituted cathinone and substituted pyrrolidine chemical classes. Its structure is comprised of hexanal bound to a phenyl ring at the 1 position and the nitrogen of a pyrrolidine ring at the 2 position. α-PHP is the longer chain homolog of α-PVP, possessing an additional carbon on the alkyl side chain.
