Antibiotic impurity standards
Antibiotic impurities and related substances, used to identify and quantify the species that appear in a related-substances or stability-indicating method. Each item is documented lot by lot so that the analytical value used in a calculation can be traced back to a certificate.
66 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.
