Recertification Request Submission Form

Compound Recertification Submission Form

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 unless prior arrangements have been made. Please include copy of previous CoA with the sample shipped for analysis.

If you need just NMR, Karl Fisher, HPLC purity only, or other analytical service, please use the other sample submission form - following the link below
