One standard. Every lot.
We would rather show you the report than tell you the number. Here is the standard every lot is held to, and how it is checked.
- 01
Independent
Testing is done by a laboratory in the United States that is independent of TRACEGROVE LABS and of the manufacturer. A supplier’s certificate is filed, never published as proof.
- 02
99%+ purity
Our release standard. A lot is released only when the laboratory’s report meets it. The measured figure on each COA is the laboratory’s, not ours.
- 03
Published first
The original laboratory PDF goes up before release, at an address that never changes. Replaced lots stay listed; corrections are noted, never silent.
From the manufacturer to your bench.
- 01
Received
Each lot arrives with the manufacturer’s certificate. We file it with the lot and never publish it as proof.
- 02
Tested
Vials from the lot go to a US laboratory independent of us and of the manufacturer: purity by HPLC, identity by mass spectrometry, content per vial.
- 03
Held to the standard
The lot is released only if the laboratory’s report shows 99%+ purity. A lot that falls short is not released.
- 04
Labelled
Every vial carries its lot number and a QR code that opens the lot lookup on this site.
- 05
Published, then released
The original report goes up at the lot’s permanent address before a single vial ships.
Purity, identity and content.
Purity by HPLC tells you how much of the material is the main component. Identity by mass spectrometry confirms what that component is. Content per vial is a third, separate measurement.
Crude synthesis
Straight from the reactor: the target plus related fragments.
Purified
Chromatography removes most of what is not the target.
Release standard · 99%+ purity
What the independent report must show before a lot is released.
What a COA does not say.
A certificate describes the material and methods named in that report, and nothing else.
Any other lot
A report describes one tested lot. Never use a different lot’s report as evidence for your material.
Safety or sterility
It is not a safety, sterility or fitness-for-purpose certification.
Suitability for human or veterinary use
A report says nothing about use in people or animals. Our materials are for laboratory research only.
Anything beyond the original
Our summary is a convenience. The laboratory’s original PDF controls if anything here differs.
