How it works
Name the compound, and the lot number if you have one — it is printed on the vial label. Requesting ahead of an order? Say so, and we send the certificate for the lot you would be quoted. What each document contains, and how to read the certificate, is covered on the quality page.
A certificate of analysis costs $75 per lot. The charge is the same whether the lot covers ten vials or a thousand, and it is per lot rather than per line, so an order drawing several compounds from one lot pays once. There is a box on the order form that adds one for every lot you are buying; ask here instead if you only want a specific compound, or if you are not ordering yet. Safety data sheets are not charged for.
