|Chemical structure of 2C-O|
2C-O (or 2,4,5-trimethoxyphenethylamine) is a phenethylamine of the 2C family. It is also a positional isomer of mescaline and was first synthesized by Jansen in 1931. This chemical is also called 2,4,5-TMPEA. It has structurally similar to the drugs mescaline and 2C-D.
2C-O is in a class of compounds commonly known as phenethylamines, and the full chemical name is 2-(2,4,5-trimethoxyphenyl)ethanamine.
Although not centrally active itself, 2,4,5-TMPEA appeared to potentiate the action of mescaline when employed as pretreatment 45 minutes prior to the administration of mescaline.
The toxicity of 2C-O is not known.
2C-O is unscheduled and unregulated in the United States, however its close similarity in structure to mescaline and 2C-B could potentially subject possession and sale of 2C-O to prosecution under the Federal Analog Act.
2C-O and all other compounds featuring in PiHKAL are Class A drugs in the United Kingdom.
