Everything You Need to Know About DOI: The Ultimate Guide for Canadian Researchers

Did you know that DOI (2,5-dimethoxy-4-iodoamphetamine), a potent serotonergic hallucinogen, exhibits 10-fold selectivity for 5-HT2A over 5-HT2C receptors, inducing head twitch response in rodents at doses as low as 0.1 mg/kg—making it an ideal probe for psychedelic mechanisms? As a Canadian researcher investigating hallucinogen-induced states, receptor signaling, or therapeutic potential in anxiety disorders, DOI remains a cornerstone in preclinical pharmacology. Synthesized in 1963 by Albert Hofmann, it is a Schedule I substance in Canada. However, for approved forensic or basic research, it requires Health Canada exemption. This guide synthesizes peer-reviewed data, safety protocols, and compliant sourcing from ChemLabs Canada—all for legitimate scientific inquiry.

Disclaimer: DOI is for legitimate research only. Not for human consumption. Consult Health Canada and REB guidelines.

WHAT IS DOI?

DOI is a ring-substituted amphetamine hallucinogen with high 5-HT2A affinity. Its chemical formula is C₁₁H₁₆INO₂, and it acts as a selective 5-HT2A/2C agonist. In research, it triggers visual hallucinations, head twitch, and altered perception. For example, neuroscientists use it to model LSD-like effects in receptor assays.

Chemical Structure Breakdown

DOI features a phenethylamine backbone with 2,5-dimethoxy and 4-iodo substitutions. The iodine enhances receptor selectivity.

Common Synonyms

Known as 2,5-Dimethoxy-4-iodoamphetamine, DOB, or DOI HCl. CAS: 64583-40-6; use HCl salt for solubility.

Role in Research

Probes hallucinogenic 5-HT2A signaling. Canadian labs require CCAC ethics.

HISTORY OF DOI

Synthesized in 1963 by Albert Hofmann at Sandoz as a mescaline analog. Tested in 1964; gained research traction in 1970s.

Early Discovery

Derived from DOB; first human dose 1964.
