2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone: reported identity research
This research-index record shows how 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone 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 C21 geranyl-hydroxy-pentyl 1,4-benzoquinone was isolated from high-potency Cannabis and structurally assigned using high-resolution mass spectrometry and one- and two-dimensional NMR evidence.
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 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone
| Field | Candidate registry value |
|---|---|
| Reported name | 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone |
| Molecular formula | C21H30O3 |
| Registry family | Cannabinoid Benzoquinone Type |
| Reported occurrence | Isolated From Cannabis |
| Registry subtype | Phytocannabinoid |
| Recorded aliases | 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone, geranyl hydroxy pentyl benzoquinone, C21 cannabinoid benzoquinone |
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
Biologically Active Cannabinoids from High-Potency Cannabis sativa
Radwan MM, ElSohly MA, Slade D, Ahmed SA, Khan IA, Ross SA / 2009-04-03
Support locator: Abstract; Results and Discussion for compound 9; Figure 1; Table 2; and the compound 9 Isolates entry: C21H30O3 assignment by HRESIMS, NMR/HMBC placement of geranyl and n-pentyl substituents on the 1,4-benzoquinone skeleton, and classification as a cannabis cannabinoid.
Extraction: Ai Assisted; publication approved as a research-index record, not identity verification.
Candidate evidence was checked against the primary article's full text; family classification and origin remain human-review items and no approval was applied.
Candidate identifiers
External identifiers are recorded with limits
| System | Value | Source note |
|---|---|---|
| PubChem CID | 44139743 | PubChem compound record with the exact title and matching C21H30O3 formula; supports chemical identity, not biosynthesis or pharmacology. |
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 source classifies this as a new cannabinoid and the second reported 1,4-benzoquinone derivative isolated from cannabis. Human review must confirm the cannabinoid-family classification without converting structural or isolation evidence into pharmacology or a living-plant biosynthesis claim.
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 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone 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.
