In rare cases, for purity estimations and mass, alternative validated methods such as 1H-NMR, ELSD (Evaporative Light Scattering Detection), GC (Gas Chromatography), or GCMS may be used when standard tests are not feasible.

Additional data such as C-NMR, 13C-DEPT, HMBC-NMR, HMQC-NMR, COSY-NMR, NOESY-NMR, NOE-NMR, CHN Analysis, Water Content, Structure Elucidation Reports, and more will be provided upon request for an additional fee.

For other categories like Building Blocks and Intermediates, we provide CoA with HPLC purity on request.

This ensures you have all the necessary analytical data to verify the quality and identity of your impurity standards.
