Source-derived summary

2C-G-4, also known as 2,5-dimethoxy-3,4-(tetramethylene)phenethylamine or as 6-(2-aminoethyl)-5,8-dimethoxytetralin, is a chemical compound 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 two additional carbon atoms to form a cyclohexane ring attached to the benzene ring and hence has a tetralin (1,2,3,4-tetrahydronaphthalene) ring system.

The compound was included by Alexander Shulgin as an entry in his 1991 book PiHKAL (Phenethylamines I Have Known and Loved). However, Shulgin was unable to complete the last step of the chemical synthesis of the compound and never tested it. In any case, he anticipated that it would be an active compound. The synthesis of 2C-G-4 has been described.

2C-G-4 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

This brief starts where responsible research should: with the source description of “2C-G-4” as chemical compound. Everything that follows is an evidence route, not borrowed authority.

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. The account is most persuasive where 2C-G-4, chemical and compound can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.

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 Feb 23, 2026. The linked authority identifier is Q9131773. 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 source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
