All compounds will ship with a current Certificate of Analysis. You can download recent CoAs for most products and you will see that identity and purity are verified by several methods. Actual Lot NMR spectra and the HPLC chromatogram are included in the CoA. Target HPLC purities for all our compounds are >98%. On the rare occasion where the HPLC purity is less than ideal we will say so. We pride ourselves on the rigour with which we test our compounds, and the descriptive format of our CoAs allows you to see and assess for yourself the validity of our conclusions. All of our work including CoA preparation is performed according to our Laboratory Manual (a document outlining our policies and procedures) which has passed vigorous, customer audits with no compliance issues. Please note that we have not sought GLP or ISO registration.

Newly prepared unlabelled compounds receive a 1-year re-test date. This is extendable to 5 years as storage and stability history is acquired. Isotope labelled compounds receive a default 5-year re-test date. All compounds shipped to you will have at least 6 months to re-test date.

Shipment by Fedex International Priority is included in the price.
