The IUPAC name for a-PHP is (±)-1-Phenyl-2-(1-pyrrolidinyl)-1-hexanone. a-PHP is a popular synthetic stimulant of the cathinone and 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.
