Quality Assurance
Certificates of Analysis
Transparency is foundational to everything we do. Every batch of every product is tested by independent, accredited laboratories and documented in a Certificate of Analysis.
What Is a COA?
A Certificate of Analysis is an official document issued by an independent laboratory that confirms a compound's identity, purity, and quality.
Each COA contains detailed analytical data including HPLC purity percentages, mass spectrometry results, and additional quality metrics. This ensures that every product you receive has been independently verified before it reaches your lab.
