Certificate of Analysis
Select a compound to view its batch-specific Certificate of Analysis, including independently verified identity, purity, endotoxin and heavy metal testing.
Clear data, not vague claims.
Every batch is independently verified before release and supported by its own Certificate of Analysis. Rather than relying solely on supplier documentation, each batch is assessed on its own merits and supported by clear, traceable evidence.
Verification system
Every batch follows the same structured verification process before release.
- HPLC purity analysis, typically 99%+.
- LC-MS identity confirmation.
- Endotoxin screening performed on every batch.
- Heavy metal screening performed on every batch.
- Unique batch reference assigned.
- Supported by a batch-specific Certificate of Analysis.
Verification approach
Every batch is assessed on its own merits. We don't rely on generic paperwork, recycled certificates or supplier claims alone.
Independent testing
Independent laboratories verify identity, purity, endotoxins and heavy metals using recognised analytical methods.
Batch traceability
Every Certificate of Analysis relates to a single production batch. No reused certificates or generic documentation.
Our verification standard
Every batch follows the same verification standard before it is approved for release.
