Other chemical names for 4-Fluoromethylphenidate are: 4F-MPH, 4-FMPH, Methyl 2- (4-fluorophenyl) -2- (piperidin-2-yl) acetate. The formula of the composition is C14H18FNO2. 4F-MPH is a molecule with a purity of 98.5% and a molecular weight of 251.3 g / mol. 4-Methylpentedrone is a fairly new Research Chemical on the market. Because this Research Chemical has been on the market for a relatively short time, little information about the substance is available. Be extremely careful when researching to and from 4F-MPH. It is known that this research chemical has many comparisons with the well-known Ritalin, also known as the drug Methylphenidate.


4F-MPH is a synthetic molecule of the substituted phenethylamine and substituted phenidate classes, and a fluorinated analog of methylphenidate. It contains a phenethylamine nucleus with a phenyl ring attached to an amino NH2 group via an ethyl chain. It is structurally similar to amphetamine, with a substitution at Rα included in a piperidine ring terminating at the terminal amine of the phenethylamine chain. In addition, it contains a methyl acetate bound to Rβ or its structure. 4F-MPH is structurally identical to methylphenidate with the exception of a single fluorine atom bonded to the four position on the phenethylamine nucleus.
