4F-PHP

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
