4F-PHP may also go by the name 4-fluro-pyrrolidinohexiophenone. It is an analog of the compound alpha-pyrrolidinohexiophenone with 4F-PHP distinguished from its parent compound by having the aromatic ring fluorinated in the para position. Fluorination of drug compounds can sometimes increase bioavailability and lipophilicity and the highly electronegative character of fluorine can change the topographical charge of the molecule interfering with metabolism and giving the compound a longer half-life. The electronegative fluorine atom should make the carbonyl less polar and reduce the reactivity of the compound. Where to buy 4F-PHP online.

4F-PHP belongs to the class of chemicals known as substituted cathinone. The substituted cathinone is a series of compounds that feature a phenethylamine backbone with a ketone at the beta carbon and various alkyl moieties substituted at the alpha carbon adjacent to the amine. 4F-PVP and -PHP has a butyl substitute at the alpha carbon. This confers increased lipophilicity to this particular cathinone. Buy 4F-PHP Online, The nitrogen itself is transformed into a pyrrolidine moiety as it forms a five-member ring with four other carbons. Many of the cathinone compounds have stimulatory effects when consumed. Some induce states of euphoria and some act as entactogens. They are related to the chemical compound cathinone, a substance derived from the plant Khat which is native to the horn of Africa.
