certificates of analysis
Every lot is assayed by reverse-phase HPLC and confirmed by mass spectrometry before release. Search a compound or lot number below, then open the lot-matched report — it is also enclosed with the shipment.

No lot records have been published yet. Request a report by email and we will send the lot-matched certificate.
what a report contains
Reverse-phase HPLC chromatogram with peak-area purity, mass-spectrometry identity against the expected sequence mass, appearance, and the assay date.
independent verification
Randomised lots go to an independent analytical laboratory. Those third-party reports are available on request for any batch we have shipped.
research use only
Analytical documentation describes chemical identity and purity only. It is not a claim of safety, efficacy or suitability for human or veterinary use.
