For anybody interested in the methylphenidate family of chemicals, 3,4-CTMP offers a legal means by which to conduct comparable research into these psychostimulants.


3,4-Dichloromethylphenidate (also known by the incorrectly abbreviated name 3,4-CTMP) is a stimulant substance of the phenidate class.3 4-ctmp buy, hdmp-28, isopropylphenidate, 4-methylmethylphenidate, 4f-mph vs Adderall

It is a structural analog of methylphenidate (Ritalin). The two substances have similar pharmacological profiles but different subjective effects.

It is approximately seven times more potent than methylphenidate in animal studies but likely has weaker reinforcing effects due to its slower onset of action.

According to anecdotal reports, the active dose of it is approximately 10 times lower than the dose of methylphenidate to achieve a similar effect.

3,4-CTMP has a duration of 6 to 18 hours rather than the 4 to 6-hour duration found with methylphenidate.

3,4-CTMP has an extremely short history of human recreational use and has yet to be documented being sold on the streets.

It is available for sale as a grey market research chemical by online vendors.

Due to its potent stimulant effects, habit-forming properties as well as an unknown toxicity profile, it is strongly recommended that one use proper harm reduction practices if using with this substance.

3,4-CTMP, or 3,4-dichloromethylphenidate, is a synthetic molecule of the substituted phenethylamine and substituted phenidate classes.

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 R which is incorporated into a piperidine ring ending at the terminal amine of the phenethylamine chain

Additionally, it contains a methyl acetate bound to R of its structure and is chlorinated at R3 and R4 of its phenyl ring.3 4-ctmp buy, hdmp-28, isopropylphenidate, 4-methylmethylphenidate, 4f-mph vs Adderall

It is nearly identical in structure to methylphenidate; the difference is that it contains two chlorine atoms bonded to the phenyl group at the 3 and 4 positions.

3,4-Dichloromethylphenidate (hydrochloride) is an analytical reference material that is structurally categorized as an amphetamine.hdmp-28

Its threo-diastereomer, 3,4-CTMP, can inhibit dopamine uptake through the dopamine transporter with an IC50 value of 65 nM in rat striatal tissue. This product is intended for research and forensic studies.isopropylphenidate, 4-methylmethylphenidate. 4-cl-PVP
