2c-g 2c-g 2c-g is a psychedelic phenethylamine of the 2c family. first synthesized by alexander shulgin, it is sometimes used as an entheogen. it has structural and pharmacodynamic properties similar to 2c-d and ganesha. like many of the phenethylamines in pihkal, 2c-g and its homologs have only been taken by shulgin and a small test group, making it difficult to ensure completeness when describing effects. 2c-g names preferred iupac name 2-(2,5-dimethoxy-3,4-dimethylphenyl)ethan-1-amine identifiers cas number 207740-18-9 y 3d model (jsmol) interactive image chembl chembl127202 y chemspider 21106224 y pubchem cid 22238091 unii dtg7fmo01j y comptox dashboard (epa) dtxsid70174848 inchi inchi=1s/c12h19no2/c1-8-9(2)12(15-4)10(5-6-13)7-11(8)14-3/h7h,5-6,13h2,1-4h3 ykey: nfohglkglzihjq-uhfffaoysa-n yinchi=1/c12h19no2/c1-8-9(2)12(15-4)10(5-6-13)7-11(8)14-3/h7h,5-6,13h2,1-4h3key: nfohglkglzihjq-uhfffaoyax smiles coc1c(c)c(c)c(cc1ccn)oc properties chemical formula c12h19no2 molar mass 209.289 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references chemistry 2c-g is 3,4-dimethyl-2,5-dimethoxyphenethylamine, with the formula c12h19no2. dosage and effects in shulgin's book pihkal, the dosage range is listed as 20 to 35 mg. effects are similar to the related ganesha, and are extremely long lasting; the duration is 18–30 hours. visual effects are muted or absent, and it is described in pihkal as an "insight-enhancer". unlike other members of the 2c family, 2c-g is nearly as potent as its amphetamine cousin. homologs several homologs of 2c-g were also synthesized by shulgin. these include 2c-g-3, 2c-g-5, and 2c-g-n. some, such as 2c-g-1, 2c-g-2, 2c-g-4, and 2c-g-6 are possible to synthesize in principle but impossible or extraordinarily difficult to do so in practice. 2c-g-1 cas: 2888537-47-9 the synthesis of this compound has not been reported, but it is described prophetically in wo2022271982 2c-g-1 2c-g-2 cas: 2888537-48-0 the synthesis of this compound has not been reported, but it is described prophetically in wo2022271982 2c-g-2 2c-g-3 cas: 207740-19-0 dosage: 16–25 mg duration: 12–24 hours effects: some visual effects. general euphoria with an underlying sense of paranoia. 2c-g-3 2c-g-4 cas: 952006-59-6 synthesized but not tested. 2c-g-4 2c-g-5 cas: 207740-20-3 dosage: 10–16 mg duration: 32–48 hours effects: similar to 2c-b for some users. general euphoria (sometimes followed by irritability), often leading to tiredness (likely due to duration). 2c-g-5 2c-g-6 cas: 2888537-49-1 the synthesis of this compound has not been reported, but it is described prophetically in wo2022271982 2c-g-6 2c-g-n cas: 207740-21-4 dosage: 20–40 mg duration: 20–30 hours effects: stimulation similar to that caused by amphetamines. general sense of unease or unfriendliness for most. 2c-g-n is sometimes called 2c-nph due to the naphthalene portion of the molecule. 2c-g-n legal status canada as of october 31, 2016; 2c-g is a controlled substance (schedule iii) in canada. united kingdom 2c-g and all other compounds featuring in pihkal are class a drugs in the united kingdom. united states in the united states 2c-g is considered a schedule 1 controlled substance as a positional isomer of 2c-e and 2,5-dimethoxy-4-methylamphetamine (dom).
