(-)-7-hydroxycannabichromane: reported identity research

This research-index record shows how (-)-7-hydroxycannabichromane 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.

Published

Reported in research

The page names the source, evidence role, and precise location used by the candidate registry.

Ongoing

Identity review

The compound remains in the registry-gated lane until a distinct human identity-verification decision is recorded.

Not assessed here

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: Negatively rotating 7-hydroxycannabichromane was isolated from high-potency Cannabis and assigned by high-resolution mass spectrometry, NMR, COSY, and HMBC 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.

Names and classification recorded for (-)-7-hydroxycannabichromane

FieldCandidate registry value
Reported name(-)-7-hydroxycannabichromane

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 3; Table 1; and the compound 3 Isolates entry: C21H32O3 assignment by HRESIMS, NMR/COSY/HMBC placement of the C-7 hydroxy group, negative optical rotation, and the explicit statement that relative configuration at C-7 could not be determined.

Extraction: Ai Assisted; publication approved as a research-index record, not identity verification.

Candidate evidence was checked against the primary article's full text; unresolved C-7 configuration remains explicit and no approval was applied.

Candidate identifiers

External identifiers are recorded with limits

SystemValueSource note
PubChem CID44139610PubChem compound record titled (-)-7-hydroxycannabichromane with the matching C21H32O3 formula; its structure does not resolve the C-7 configuration, matching the primary paper's explicit uncertainty.

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 primary paper explicitly states that the relative configuration at C-7 could not be determined because too little material was available. The PubChem title repeats the negative optical-rotation name but its structure record does not resolve that stereocenter; human review must not infer a C-7 configuration.

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 (-)-7-hydroxycannabichromane 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.

Corrections and review

Help us improve the source trail

If a structure assignment has been corrected, a source has been retracted, an identifier is mismatched, or a stronger identity record exists, send the DOI or PMID and a precise locator. The editorial team can review the evidence and preserve the decision history.
