4F-PHP is a relatively new research chemical, is a synthetic stimulant. The research chemical 4F-PHP has an IUPAC name of 1-(4-fluorophenyl)-2-(pyrrolidin-1-yl)hexan-1-one, an exact mass of 263.17, and a molecular weight of 263.35. The chemical formula for the new research chemical is C16H22FNO.
Its action is similar to a-PVP.
At the moment very little data exists about the pharmacological properties, metabolism, and toxicity of 4F-PHP. 4F-PHP is available for purchase on www.sale-chemicals.com as a new research chemical.
4F-MPH ( known as 4-Fluoromethylphenidate) is a novel synthetic stimulant of the substituted phenethylamine and piperidineclasses that produces long-lasting euphoriant, and stimulating effects when administered. It is a closely related structural analog of the commonly prescribed ADHD drug methylphenidate.
The two substances are believed to have very similar pharmacological mechanisms as monoamine reuptake inhibitors but have been reported to display distinctive subjective effects, with 4F-MPH being considered significantly more euphoric and recreational. Anecdotal reports suggest that it is considerably more potent with fewer uncomfortable side effects such as anxiety, muscle spasms and compulsive redosing. This perhaps owes to the fact that it has been shown to act as a higher efficiency dopamine reuptake inhibitor than the parent compound methylphenidate.
4F-MPH has an extremely short history of recreational use and has yet to be documented being sold on the streets. It was initially developed as a replacement for ethylphenidate which became illegal in the United Kingdom on April 2015 following a temporary blanket ban. Shortly after, it recently became made available for sale on the online gray market as a research chemical for global distribution.
Due to its potent, long-lasting stimulant effect, likely habit-forming properties as well as unknown toxicity profile, it is strongly recommended that one use proper harm reduction practices if choosing to use this substance.
4F-MPH is a synthetic molecule of the substituted phenethylamine and piperidine classes, and a fluorinated analog of methylphenidate. It contains a phenethylamine core featuring a phenyl ring bound to an amino -NH2 group through an ethyl chain. It is structurally similar to amphetamine, featuring a substitution at Rα which is incorporated into a piperidine ring ending at the terminal amine of the phenethylamine chain. Additionally, it contains a methyl acetate bound to R2 or its structure. 4F-MPH is structurally identical to methylphenidate with the exception of a single fluorine atom bound to the four position on the phenethylamine core.
4-Fluoromethylphenidate (also known as 4-FMPH and 4F-MPH) is a stimulant drug that acts as a higher potency dopamine reuptake inhibitor than the closely related methylphenidate.
