Use the COA lookup to search by compound or lot number. The matching certificate also travels with your order, and every lot is archived publicly.

Products are supplied as a lyophilized powder — shelf-stable and sealed against light and moisture, with no cold chain required for shipping. For long-term storage, keep lyophilized material at −20°C, protected from light. Storage guidance is listed on each product page.

In-stock orders are dispatched the same or next business day with tracking. Shipping is free on orders over $250, and expedited options are available at checkout. See Shipping for details.

Because these are research chemicals, all sales are final — we do not accept returns, issue refunds, or cancel or modify orders once placed. If a lot arrives damaged or fails to match its COA, the purity-match guarantee applies. Review your cart carefully before checkout.
