EVERYTHING YOU NEED TO KNOW ABOUT 2C-I: THE ULTIMATE GUIDE FOR CANADIAN RESEARCHERS

Did you know that 2C-I (2,5-dimethoxy-4-iodophenethylamine) remains one of the most visually intense compounds in the 2C family, producing fractal-like patterns and deep synesthesia at just 10–25 mg while reliably inducing the head-twitch response at 0.3 mg/kg in rodents? As a Canadian researcher studying 5-HT2A receptor activation, visual cortex plasticity, or psychedelic-assisted therapy models, 2C-I delivers a clean, colorful, and highly predictable profile. Synthesized in 1991 by Alexander Shulgin, it is a Schedule I substance in Canada. However, for authorized forensic or preclinical research, it requires Health Canada exemption. This guide provides peer-reviewed data, safety protocols, and compliant sourcing from ChemLabs Canada—strictly for legitimate scientific use.

Disclaimer: 2C-I is for legitimate research only. Not for human consumption. Always follow Health Canada and REB guidelines.

WHAT IS 2C-I?

2C-I is a ring-substituted phenethylamine hallucinogen of the 2C series. Its chemical formula is C₁₀H₁₄INO₂, and it acts as a highly selective 5-HT2A receptor agonist. In research, it produces intense visual geometry, color saturation, and mild euphoria lasting 6–10 hours. For example, neuroscientists use it to study hallucinogen-induced cortical excitation.

Chemical Structure Breakdown

2C-I features a phenethylamine backbone with 2,5-dimethoxy and 4-iodo substitutions. The iodine atom dramatically increases receptor affinity.

Common Synonyms

Known as 2,5-Dimethoxy-4-iodophenethylamine, 2C-I HCl. CAS: 69587-11-7; supplied as HCl salt for solubility.

Role in Research
