Usually these are the counterparts of international standards. Noncompendial. Select "Continue session" to extend your session. Actual and potential degradation products should be isolated and identified during development of the reference standard. Their purity requirements, hoewver, are generally not as stringent. Different types of reference-standard materials and the qualification tests recommended are presented in Table II. 3. Applicants that use proprietary materials will find that primary standards are not typically available through compendial sources. Table I presents recommended qualification parameters compared with reference-standard material type. The critical characteristics of each lot of specimen selected for the standard are usually determined independently in three or more laboratories. Impurities classified as organic (process and drug related), inorganic, or residual solvents (4) can be introduced during the manufacturing process for the drug substance, drug product, or excipient and/or through storage of the material. How to enter Lot Number (COA) Search . Usually these are the counterparts of international standards. Materials can be developed or purchased from chemical-supply companies for use as in-house secondary reference standards even when compendial reference standards are available.
