4F-MPH is a research chemical that is also known as 4-Fluoromethylphenidate and 4-FMPH and is classified as a stimulant. It is also known to be in the substituted classes of piperidine and phenethylamine. 4F-MPH is very closely related to the prescription medication methylphenidate which is prescribed for those with ADHD. 4F-MPH through studying different compounds and comparison studies that this research chemical that is purchased by the manufacturer for research purposes, shows to have a higher efficiency when it comes to being a reuptake inhibitor of dopamine than the medication methylphenidate. This would mean that 4-Fluoromethylphenidate would display more euphoric effects than the parent medication.
At this time, however, there has been no research on human usage and it is still classified as a research chemical and is therefore not intended for human consumption.

Manufacturers of 4F-MPH developed this chemical with the hopes of being a substitute for ethylphenidate with stronger effects medically but less bad side effects including compulsive redosing, muscles spasms, and anxiety.

Through an ethyl chain, there is an amino NH2 group that has a phenyl ring bound to it but the chemical structure of 4f-MPH is very closely related to amphetamine as it has a Ra substitution in a piperidine ring. Along with this, its structure has a methyl acetate bound to R2. This research chemical has one difference from methylphenidate which is the at the four position on the phenethylamine core there is a bonded fluorine atom.

It is believed that 4F-MPH is an analog of amphetamine but that is more potent due to the fact that it contains methyl groups. Bromine groups, chlorine groups, and fluorine groups. Research on these compounds shows that 4F-MPH is a reuptake inhibitor of dopamine which means that it binds dopamine neurotransmitters and blocks a bit of the transportation of proteins which would allow stronger euphoric and stimulating effects as the dopamine stays in the brain longer.

Studies have been conducted to discover if the research chemical could be used as an anti-cocaine medication but the data for this report has not been completed at this time. Therefore, it is important to note that 4f-MPH is a research chemical and not intended for human consumption.
No countries have classified this compound as a controlled substance, however, the state of Alabama in the United States has it listed as such. Other states, as well as countries, can purchase 4f-mph for further studies to determine any benefits that this compound may have for humans.
