The reference standard should be of the highest purity possible; the drug substance may require further purification to become a reference standard (additional purification steps used for a drug substance should be fully described and included in any regulatory filing). 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. Metals impurityICP with MS detection or ICP with optical-emission spectroscopy detection, Noncombustible impuritiesresidue on ignition, Residual solventsGC with flame ionization detection, Structural confirmation: hydrogen and carbon13 NMR, LCMS, or FTIR.

Additional testing may be required to identify and quantify known or potential impurities that may have been overlooked during the manufacturer's assessment of the material. Degradation products and compounds related to the product can be evaluated by the area percent or from the relative response of the standard being used. Two columns appear in the Catalog to identify the current official lots. 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. On the 23rd February, AXIO, Dr Ehrenstorfer and Digamma Consultancy will come together to answer your questions on cannabis testing. 1.

These two sections are reprinted here for your reference. In this case, where the reference standard is the sample, the parameters validated are restricted. Residual solvents, however, may be specific to the manufacturing process and require a specific test procedure. If there was 1% impurity based on area percent present, however, then there would be 2% of actual impurity that could affect overall purity. Properties Reference standards that contain a high percentage of organic volatile impurities may experience purity changes over time as the solvents evaporate. Labs, Inc. 1985 - 2023 I.V.

In such cases, measurements are made on preparations of both the test specimen and the Reference Standard. The relative-response factor approach requires additional development because the component needs to be isolated and the relative response factor must be determined. USP currently offers more than 3,500 Reference Standardshighly characterized specimens of drug substances, excipients, food ingredients, impurities, degradation products, dietary supplements, compendial reagents and performance calibrators. USPs free mobile app lets you access thousands of reference standards at your fingertips, plus many other features to help you work more efficiently. USP monographs include the name of the ingredient or preparation; the definition; labeling, packaging, storage requirements; and the specifications, which consist of a series of tests, procedures for the tests, and acceptance criteria. 2023 MJH Life Sciences and Pharmaceutical Technology. Both the core name (ex. Click here to subscribe to our newsletter, The Standard, to receive a monthly snapshot of new and updated RS's. Supelco. 6. The synthesis of the reference standard should be evaluated to predict and identify potential impurities from raw materials. Elemental analysis, titration, GC, or LC can be used for purity determination. The approach to determining the relative-response factor for each impurity is a more accurate process, but potential pitfalls should be considered. The USP Reference Standards Committee collaborates closely with the WHO in order to minimize unavoidable differences in the actual units of potency, and in some cases to share in the preparation of a reference standard. Consider a reference standard that is 90% pure. ICH, Q2(R1) Validation of Analytical Procedures: Text and Methodology (Geneva, Switzerland), Oct. 1994.
