Source-derived summary

2C-G-3, also known as 2,5-dimethoxy-3,4-(trimethylene)phenethylamine, is a psychedelic drug of the phenethylamine and 2C families. It is the derivative of 2C-G (2C-G-0) in which the 3,4-dimethyl groups have been connected via an additional carbon atom to form a cyclopentane ring attached to the benzene ring and hence has a dihydroindene ring system.

In his 1991 book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists 2C-G-3's dose as 16 to 25 mg orally and its duration as 12 to 24 hours. The effects of 2C-G-3 were reported to include "lots of LSD-like sparkles", easier communication, impairment, and social avoidance, among others. One report remarked that it was "marvelous".

The chemical synthesis of 2C-G-3 has been described.

The drug was first described in the literature by Shulgin in PiHKAL in 1991. It is a controlled substance in Canada under phenethylamine blanket-ban language.

Editorial summary

The public source identifies “2C-G-3” as chemical compound. This brief keeps that definition visible, then builds a research path around 2C-G-3, chemical and compound.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1991—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with 2C-G-3, chemical and compound providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “2C-G-3”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q9131771. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1991.

Critical limits

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.
