Lab Testing & Certificates

Purity is the whole point of a reference standard. Every compound we supply is independently analysed before it reaches you — and the results are documented, not just claimed.

How we verify every batch

• HPLC purity: High-performance liquid chromatography quantifies molecular purity against reference peaks — every catalogue SKU is verified to > 99%.
• Mass spectrometry: Mass-spec confirms the exact molecular weight and identity of each compound, ruling out mislabelled or substituted material.
• Signed COA: A Certificate of Analysis is compiled and signed by the testing directors for each batch, recording the chromatogram and results.

What every Certificate of Analysis confirms

• Compound name, batch reference and test date
• Measured purity (%) by HPLC, with the chromatogram
• Molecular identity confirmed by mass spectrometry
• Appearance, and the signing testing director

Certificates of Analysis are being finalised for each product and will be published here soon. In the meantime, contact us to request the COA for a specific batch.
