Reported cannabinoid research / identity review ongoing
Cannabitwinol: reported identity research
This research-index record shows how Cannabitwinol has been described in cited chemical-identity research. It is a source map, not an independent chemistry verification and not a page about health effects.
Publication status
Research index published; compound identity not independently verified
A human approved publication of this source-linked record on July 24, 2026. That editorial decision allows the cited identity report and its locator to be indexed. It does not verify the chemical identity, approve a health claim, establish safety, or convert AI-assisted extraction into a scientific conclusion.
Reported in research
The page names the source, evidence role, and precise location used by the candidate registry.
Identity review
The compound remains in the registry-gated lane until a distinct human identity-verification decision is recorded.
Effects and safety
This identity record does not make a clinical, therapeutic, dosing, product, or personal-safety claim.
What the registry records
Source-linked identity summary
Our candidate registry summarizes the cited identity record this way: A symmetric methylene-bridged cannabidiol dimer isolated in pure form from an industrial hemp extract and structurally characterized by high-resolution mass spectrometry and low-temperature one- and two-dimensional NMR.
This wording is deliberately limited to identity and occurrence. “Reported,” “isolated,” “detected,” or “characterized” describes what the cited paper says it did; those words do not mean Cannabinoid Encyclopedia independently repeated the laboratory work. The original source and locator below are the controlling evidence trail.
Candidate identity snapshot
Names and classification recorded for Cannabitwinol
| Field | Candidate registry value |
|---|---|
| Reported name | methylene-bridged cannabidiol dimer |
| Molecular formula | C43H60O4 |
| Registry family | Dimeric Cannabidiol |
| Reported occurrence | Isolated From Cannabis |
| Registry subtype | Phytocannabinoid |
| Recorded aliases | CBDD, cannabitwinol, CBD dimer |
These fields help readers find the cited record and distinguish similarly named compounds. They remain candidate metadata while identity review is ongoing. A molecular formula or familiar abbreviation alone is not proof that two records describe the same material, stereochemistry, preparation, or natural occurrence.
Identity evidence trail
1 identity record from 1 peer-reviewed source
Each entry states why a source was connected to this candidate and where its support should be checked. Readers should inspect the cited paper when exact analytical methods, spectra, comparison standards, stereochemistry, or sample provenance matter.

Isolation And Structure Elucidation
Cannabitwinol, a Dimeric Phytocannabinoid from Hemp, Cannabis sativa L., Is a Selective Thermo-TRP Modulator
Chianese G, Lopatriello A, Schiano-Moriello A, et al. / 2020-09-03
Support locator: Abstract; Results section 'Isolation and Structural Characterization of Cannabitwinol', including the C43H60O4 HR-ESIMS assignment and low-temperature 2D NMR analysis; Experimental section 'Plant Material and Isolation of Cannabitwinol'.
Extraction: Ai Assisted; publication approved as a research-index record, not identity verification.
Candidate identity evidence extracted for human verification; formation route and industrial-extract boundary are flagged and no approval was applied.
Candidate identifiers
External identifiers are recorded with limits
| System | Value | Source note |
|---|---|---|
| No external identifier recorded | — | The research-index page does not assign an identifier that is absent from the candidate registry. |
An identifier can help locate a database record. It does not by itself establish that a compound was naturally present in a sample, that a published structure assignment is final, or that a commercial product contains the reported compound.
Mandatory editorial note
What must stay attached to this record
The paper presents enzymatic formation as a hypothesis, not a demonstrated biosynthetic route. Isolation from an industrial extract does not exclude postharvest or processing formation. A PubChem structure record lacks an authoritative cannabitwinol name association, so no identifier was imported.
The source extraction was prepared for human review and the page publication was approved as a research-index record. A later identity decision may verify, revise, merge, exclude, or supersede this candidate. Corrections should preserve the prior evidence trail rather than silently overwriting it.
What this page cannot answer
Identity research is not an effects guide
- This page does not establish that Cannabitwinol has a health benefit or treats a condition.
- It does not establish human safety, intoxication risk, interactions, dosing, or suitability for any person.
- It does not verify a retail product, label, certificate of analysis, extract, or formulation.
- It does not transfer findings from THC, CBD, another cannabinoid, an animal model, or a laboratory assay to this candidate.
- It does not replace the original analytical paper or a qualified chemical review of that paper.
