What a COA (Certificate of Analysis) Should Include Identity Confirmation Mass spectrometry confirming molecular weight ~419.4 Da (molecular formula C22H21N5O3) NMR or LC-MS/MS structural confirmation for a small molecule (peptide vendors often skip this small-molecule identity confirmation is non-negotiable here) Purity Testing HPLC purity 98%+ minimum Single dominant peak on the HPLC chromatogram Contamination Testing Residual solvent panel (DMSO, ethanol, acetone all common in small-molecule synthesis) Heavy metals screen Endotoxin testing if the product is positioned for injectable use How to Verify a COA Is Legitimate Match lot number to batch
