Quality

Our quality standard

Research results are only as reliable as the materials behind them. Our quality process is built to remove doubt at every step.

99% or greater purity

Every compound in our catalog is manufactured to a minimum of 99% purity. Purity is not a marketing number; it is a specification each batch must meet before it is released for sale.

Third-party verification

Independent laboratories verify identity and purity for each batch. The Certificate of Analysis for each lot is published on the product page and on the CoA lookup page, and batch records are retained so any vial can be traced back to its testing.

Handling and storage

Compounds are shipped lyophilized in sealed vials. Store vials cold and away from light: refrigeration is acceptable short term, and freezing is recommended for long term storage. Specific guidance is listed with each product.
