3,4-dichloromethylphenidate 3,4-dichloromethylphenidate 3,4-dichloromethylphenidate (also known as 3,4-ctmp or 3,4-dcmp) is a stimulant drug related to methylphenidate. dichloromethylphenidate is a potent psychostimulant that acts as both a dopamine reuptake inhibitor and norepinephrine reuptake inhibitor, meaning it effectively boosts the levels of the norepinephrine and dopamine neurotransmitters in the brain, by binding to, and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft. 3,4-dichloromethylphenidateclinical dataroutes ofadministrationoralatc codenonelegal statuslegal status ca: schedule iii de: npsg (industrial and scientific use only) uk: class b identifiers iupac name methyl (2r)-2-(3,4-dichlorophenyl)-2-acetate cas number210776-65-1 y (racemic)1364331-88-3 (r,r)pubchem cid44296390chemspider23104857 yuniif7ln3n6zlacomptox dashboard (epa)dtxsid30658831 chemical and physical dataformulac14h17cl2no2molar mass302.20 g·mol−13d model (jsmol)interactive image smiles n2ccccc2c(c(=o)oc)c(cc1cl)ccc1cl inchi inchi=1s/c14h17cl2no2.clh/c1-19-14(18)13(12-4-2-3-7-17-12)9-5-6-10(15)11(16)8-9;/h5-6,8,12-13,17h,2-4,7h2,1h3;1h/p-1/t12-,13+;/m1./s1 ykey:djqisaowjxqdpu-kzczeqiwsa-m y ny (what is this?) (verify) 3,4-dcmp, the threo-diastereomer, is approximately seven times more potent than methylphenidate in animal studies, but has weaker reinforcing effects due to its slower onset of action. however, h. m. deutsch's discrimination ratio implies it to be more reinforcing than cocaine. legality as of october 2015 3,4-ctmp is a controlled substance in china. 3,4-ctmp was banned in the uk as a temporary class drug from april 2015 following its unapproved sale as a designer drug. sweden's public health agency suggested to classify 3,4-ctmp as hazardous substance on 10 november 2014.
