Impurity and metabolite reference standards
Impurity, metabolite and related-substance standards for pharmaceutical and analytical work. What makes a standard usable is not the pack size but the documentation behind it: identity confirmation, the analytical method and the assigned content.
123 items in this group. Every one has its own page with the CAS number, molecular data, available pack sizes and the documentation on file; the batch certificate of analysis states the value assigned to the lot you receive.
