Useful information
Reference standards are needed for identification, assay and impurity control of medicinal products. EDQM, USP and British Pharmacopoeia standards are used in tests according to the corresponding pharmacopoeial monographs.
Secondary standards (for example, Pharmaceutical Secondary Standards) are traceable to primary pharmacopoeial standards and suit routine control. Custom synthesis manufacturers supply impurity standards and labelled compounds in any pack size on request.
