What the grade actually means.
Suppliers sell “API-grade”, “GMP” and “pharma-grade” cannabinoids. Three of those phrases have precise meanings and one has none at all. This section says which is which, what a buyer should ask for, and — compound by compound — exactly where Peregrine stands today and what it is working toward.
Start with the words
Four phrases carry almost every question that reaches this desk. Three of them have precise meanings a supplier can be held to. One has none.
- What is an API (active pharmaceutical ingredient)?The regulatory definition, the five things it actually requires, and why a purity figure is not one of them.
- API grade vs research grade: what actually changesThe molecule is the same. What differs is how much of its history is documented, and who answers for it.
- Where do I buy a cannabinoid reference standard?Who actually sells them, what the certificate must say, and why ISO 17034 and 17025 are not interchangeable.
- GMP ingredients: which GMP, and what each one coversFour unrelated regimes share the word. Which certificate means what, and the three questions that settle a claim.
- What does pharma grade mean?An empty phrase doing a real job badly — and the five-line specification that replaces it.
- How do you qualify a cannabinoid API supplier?Directory listings promise DMF and CEP against compounds that can hold neither. The questions that separate a manufacturer from a broker.
Who can supply what, today
The honest version of the question every one of these pages gets asked. No row says API, and no row will until the work behind it is done and can be shown.
| Compound | API today | Compendial standard | Bulk from Peregrine | Sample |
|---|---|---|---|---|
| CBG | None anywhere | No USP · no Ph. Eur. | 5 g – 100 kg | 5 g research cut |
| CBGA | None anywhere | No USP · no Ph. Eur. | 5 g – 100 kg, shipped 2–8 °C | 5 g research cut |
| CBGV | None anywhere | No USP · no Ph. Eur. | Campaign-based; 5 g open | 5 g research cut |
| CBDV | None; Phase 2a missed endpoint | No USP · no Ph. Eur. | 5 g upward | 5 g research cut |
| THCV | None; purity short of API | No USP · no Ph. Eur. | 5 g upward, destination first | 5 g research cut |
| CBN | None; purity short of API | USP draft: impurity limit | 5 g – 100 kg | 5 g research cut |
| Cannflavin A | None; research is preclinical | No USP · mg-scale CRM only | Not yet — development target | Not yet |
Peregrine is working to supply all of it — API-grade material, certified standards and GMP-declared volume — at research and industrial scale worldwide, through its own patented synthesis process. Synthesis, registration and stability work sits with the NatSyn Lab at McMaster University, which holds the intellectual property behind the platform.
What is an active pharmaceutical ingredient?
21 CFR 210.3 defines an active ingredient as the component of a drug product intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment or prevention of disease. That definition is about the role the molecule plays in a drug, which is why the same compound can be a research chemical on one shelf and an API on another.
What makes it an API in practice is the work behind it. ICH Q7 sets good manufacturing practice for APIs, and it applies from the defined API starting material onward rather than from the field. ICH Q3A governs how impurities in a new drug substance are reported, identified and qualified. ICH Q1A sets the stability package. A Drug Master File is usually filed so a drug applicant can reference the manufacturing detail without seeing it — and a DMF is not an approval; FDA neither approves nor disapproves one.
None of that exists today for any cannabinoid Peregrine sells. Saying otherwise would be a claim about a regulated term, and the point of this section is to be the page that does not make one.
What is an analytical reference standard?
A reference standard is a highly characterised material used to identify or quantify a compound in a method. It is a different product from a bulk ingredient, sold at a different scale — milligrams in a vial with a certificate, rather than kilograms in a drum.
The compendial versions are USP Reference Standards and European Pharmacopoeia Chemical Reference Substances, the latter established under Ph. Eur. chapter 5.12 and ISO 17034. Outside the pharmacopoeias, commercial producers sell certified reference materials, and the accreditation that matters there is ISO 17034 — which covers producing a reference material, and is a different accreditation from ISO/IEC 17025, which covers running a test. A working or secondary standard is one a laboratory qualifies in house against a certified primary.
Not one of the seven compounds in this section has a USP or Ph. Eur. standard. If you need certified material this week, the commercial producers — Cayman Chemical, Cerilliant, Supelco, LGC Standards, Restek — are where it comes from, and we would rather tell you that than pretend otherwise.
Which GMP is which
Four different regimes share the abbreviation, and a certificate against one is not evidence for another. This is where most of the confusion in the cannabinoid market lives.
| Regime | Covers | What it means |
|---|---|---|
| ICH Q7 | Active pharmaceutical ingredients | The one that applies to an API. GMP from the defined starting material onward. |
| 21 CFR 210 / 211 | Finished drug products | Drug-product GMP. Not the same scope as Q7. |
| 21 CFR 111 | Dietary supplements | A separate, lighter regime. Most 'GMP certified' cannabinoid claims sit here. |
| ISO 22716 | Cosmetics | Third-party certifiable. Says nothing about drug or supplement GMP. |
There is also no registrar that issues an API GMP certificate the way one issues an ISO certificate. API GMP is demonstrated by inspection. So when a supplier says GMP, the two useful questions are which regime and who inspected the site.
Where Peregrine stands, compound by compound
Seven compounds, one page each: what the API claim would require, who sells a certified standard, which GMP a certificate is likely to name, and what ships from Peregrine today.
- CBGCBG as an API, a reference standard, and what GMP CBG meansNo approved drug uses CBG, no USP standard exists, and what GMP CBG usually means.
- CBGACBGA API status, reference standards, and what GMP means hereThe precursor acid: no monograph, no drug programme, and what its stability question is.
- CBGVCBGV: API status, reference standards, and GMP claimsThe varin branch precursor: scarce, campaign-based, no monograph.
- CBDVCBDV API status, reference standards, and a trial that missedThe one with real clinical history — and what missing an endpoint does and does not change.
- THCVTHCV as an API: where the purity falls short, plus standards and GMPWhere today's purity falls short of an API bar, stated plainly.
- CBNCBN API status, reference standards, and what a USP impurity limit is notThe only one with any pharmacopoeial presence — and why an impurity limit is not a standard.
- Cannflavin ACannflavin A as an API, a reference standard, and where supply standsA prenylated flavone, not a cannabinoid: preclinical, milligram-scale, no bulk supply anywhere.
Questions
What is an API (active pharmaceutical ingredient)?
Under 21 CFR 210.3 an active ingredient is the component of a drug product intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment or prevention of disease. ICH Q7 sets what a manufacturer must do to make one: good manufacturing practice from the defined starting material onward, an impurity profile qualified under ICH Q3A, stability data under ICH Q1A, and usually a Drug Master File a drug filer can reference. The same molecule can be a research chemical, a cosmetic ingredient or an API — what differs is the regulatory work behind it.
What is an analytical reference standard?
A highly characterised material used to identify or quantify a compound in an analytical method. USP Reference Standards and European Pharmacopoeia Chemical Reference Substances are the compendial versions; commercial producers sell certified reference materials under ISO 17034 accreditation. A reference standard ships in milligrams and is a different product from a bulk ingredient, with different accreditation behind it.
Does Peregrine sell API-grade or GMP cannabinoids today?
No. Peregrine supplies research-grade isolates at ≥99.9% with identity and assay on a certificate for each lot. It does not hold GMP certification, does not file a Drug Master File, and none of its compounds is the active ingredient of an approved drug. It is working toward supply at API and reference-standard grade.
Does any cannabinoid on this list have a USP monograph?
None of the seven has a USP Reference Standard or a European Pharmacopoeia Chemical Reference Substance. CBN appears in USP's draft cannabidiol monograph as an impurity limit, which is not the same as having a monograph of its own.
What are GMP ingredients?
Ingredients made under a documented quality system — but the word names four unrelated regimes, and a certificate against one says nothing about the others. ICH Q7 covers active pharmaceutical ingredients, 21 CFR 210 and 211 cover finished drugs, 21 CFR 111 covers dietary supplements, and ISO 22716 covers cosmetics. Ask which regime, who audited it, and for the certificate and its scope.
Where do I buy a cannabinoid API or reference standard?
No cannabinoid on this page is available as an API from anyone, because none is the active ingredient of an approved drug. Certified reference standards come from ISO 17034 reference-material producers in milligram vials. Peregrine supplies research-grade bulk isolate today, from 5 g to 100 kg, and is working toward both.
What does pharma grade mean?
It is not a defined regulatory term. No regulation fixes it, no body awards it and no test confirms it. At its most generous it means the material meets a pharmacopoeial monograph — which, for every compound on this page, does not exist. Read the specification instead.
