2,n,n-tmt 2,n,n-tmt 2,n,n-trimethyltryptamine, 2,n,n-tmt, or 2-me-dmt is a tryptamine derivative that is a psychedelic drug. it was invented by alexander shulgin and reported in his book tihkal (#34). it is claimed to show psychoactive effects at a dosage of 50–100 mg orally, but these are relatively mild compared to other similar drugs, suggesting that while the 2-methyl group has blocked the binding of metabolic enzymes, it is also interfering with binding to the 5ht2a receptor target that mediates the hallucinogenic effects of these drugs. 2,n,n-tmtlegal statuslegal status de: npsg (industrial and scientific use only) uk: class a identifiers iupac name (2-(2-methyl-1h-indol-3-yl)-1-methyl-ethyl)dimethylamine cas number1080-95-1 ypubchem cid11820174chemspider9994827uniip15uo6j3fkchemblchembl7580chemical and physical dataformulac13h18n2molar mass202.301 g·mol−13d model (jsmol)interactive image smiles cc1c(c2ccccc21)ccn(c)c inchi inchi=1s/c13h18n2/c1-10-11(8-9-15(2)3)12-6-4-5-7-13(12)14-10/h4-7,14h,8-9h2,1-3h3key:ndgcowdslvnlge-uhfffaoysa-n (verify) legal status sweden's public health agency suggested classifying 2-me-dmt as a hazardous substance, on may 15, 2019.
