2C-H (2,5-dimethoxyphenethylamine) is a lesser-known substituted phenethylamine of the 2C family.


2C-H was first synthesized in 1932 by Johannes S. Buck.[1]


2C-H is used as a precursor in the synthesis of other substituted phenethylamines such as 2C-B, 2C-I, and 2C-N.[2] 2C-H has been found in trace amounts by the DEA's south central laboratory in tablets that were suspected of containing MDMA.[citation needed]


There is no record of 2C-H trials in humans, as it would likely be destroyed by monoamine oxidase enzymes before causing any significant psychoactive effects.[2] In the book PiHKAL, Alexander Shulgin lists both the dosage and duration of 2C-H effects as unknown.[2] Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-H.


2C-H exhibits agonist activity in vitro at human trace amine associated receptor 1 expressed in RD-HGA16 CHO-K1 cells coexpressed with Galpha16 protein assessed as internal calcium mobilization.[3] 2C-H was found to be inactive in NCI In Vivo Anticancer Drug Screens for tumor model L1210 Leukemia.[3] It was found to be an active Alpha-1 adrenergic receptor agonist in rabbit ear arteries.[3] It has binding affinity towards 5-HT2C and 5-HT2A receptors in rats.[3] It features competitive antagonist activity at 5-HT serotonin receptor in Sprague-Dawley rat stomachs.[3] It exhibits binding affinity against rat 5-hydroxytryptamine 2C receptors using [3H]mesulergine as a radioligand.[3]

Legal status


As of October 31, 2016; 2C-H is a controlled substance (Schedule III) in Canada.[4]

United States

As of July 9, 2012, 2C-H is a Schedule I controlled substance in the United States, under the Synthetic Drug Abuse Prevention Act of 2012.[5] 2C-H's DEA Drug Code is 7517.
