3C (psychedelics)
class of chemical compounds
3C (3C-x), also known as 4-substituted 3,5-dimethoxyamphetamines, substituted 3,4,5-trimethoxyamphetamine (3,4,5-TMA or TMA-1) analogues, or 3C-scalines, is a general name for the family of psychedelic amphetamines containing methoxy groups at the 3 and 5 positions of the benzene ring. These compounds are analogues of 3,4,5-trimethoxyamphetamine (3,4,5-TMA or TMA-1).
The 3C drugs are not the amphetamine counterparts of the 2C drugs, which are 4-substituted 2,5-dimethoxyphenethylamines. Instead, the DOx drugs, which are 4-substituted 2,5-dimethoxyamphetamines, are the amphetamine counterparts of the 2C drugs. The 3C drugs are the amphetamine counterparts of scalines (4-substituted 3,5-dimethoxyphenethylamines). Moreover, in terms of naming with the "3C" prefix, the 3C drugs are generally actually derivatives of TMA-1 with the 4-position methoxy group extended rather than having any 4-position substituent. In this regard, they would be the 3,5-dimethoxyamphetamine counterparts of the 2C-O (2,4,5-trimethoxyphenethylamine) drugs (e.g., 2C-O-4) and the 2,4,5-trimethoxyamphetamine (2,4,5-TMA; TMA-2) derivatives (e.g., MEM).
3C drugs have been developed and/or studied by Alexander Shulgin and Daniel Trachsel, among others. The pharmacology of 3C drugs has been studied and described.
The public source identifies “3C (psychedelics)” as class of chemical compounds. This brief keeps that definition visible, then builds a research path around psychedelics, class and chemical.
Why this record matters
A short description can identify a subject without explaining its stakes. For “3C (psychedelics)”, the useful work is to connect “class of chemical compounds” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q133799828. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
