Our compound recertification service includes a comprehensive Certificate of Analysis and all supporting documentation prepared under GLP conditions. Standard certification includes UV HPLC Purity Analysis, Mass Spectrometry Analysis (m/z), and NMR Analysis (molecular structure). For compounds without adequate UV absorbance, recertification will done using 500 MHz Quantitative proton NMR (potency and structure confirmation) and Mass Spectrometry Analysis (m/z).
Minimum 5 mg of compound required for standard recertification unless prior arrangements have been made. KF titration and Optical Rotation requires at least 10 mg of compound. Please include copy of previous CoA with the sample shipped for analysis.
