View Price and Availability. . For example, if the reference-standard material is a salt, then the cation response would not be equivalent to the reference standard. Actual and potential organic impurities that arise during synthesis, purification, and storage must be identified and quantitated. You can even export bookmarked lists to send your team or send to purchasing to order more. Simply use our extensive, alphabetical library or convenient vial barcode scanner to find exactly what you need in a matter of seconds. Table I presents recommended qualification parameters compared with reference-standard material type. The US Pharmacopeia (USP) defines reference-standard materials as "highly characterized specimens of drug substances, excipients, reportable impurities, degradation products, compendial reagents, and performance calibrators" (2). Two columns appear in the Catalog to identify the current official lots. Explore our latest catalogue of research chemicals, analytical standards and the largest global collection of pathogenic virus strains. Meanwhile, where a USP Reference Standard is called for, the corresponding substance labeled as an NF Reference Standard may be used. Chemical purity must be determined for both groups; nuclidic reference standards, however, also need to be evaluated for radionuclidic and radiochemical purity. In this case, where the reference standard is the sample, the parameters validated are restricted.

To receive periodic email updates when USP posts New Official Text, sign up for the free Compendial Updates service. To serve its intended purpose, each USP Reference Standard must be properly stored, handled, and used. However, the method can be assessed for parameters applicable to evaluating the reference material. Lists of "New USP Reference Standards" and "Unavailable First-time Official USP Reference Standards" are provided below. If possible, it is recommended the reference standard be in a salt-free state to reduce the characterization tests required. 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. While USPs public health mission has remained unchanged for over 200 years, the global healthcare landscape has been anything but static. As a reminder, the USP APP is NOT meant to be, nor is it represented as being the most up to date source of information on USP Reference Standards. Reference-standard materials are often expensive to manufacture and are generally of limited supply. New and Updated Interim Revision Announcements. Determination of organic impurities is the most challenging aspect of developing a suitable analytical method because these impurities are unique to the parent compound and because various degradation pathways can lead to various impurities. For further information on this product, please consult its ATCC.org product page under General Information, Permits and Restrictions and BSL.

While USP's public health mission has remained unchanged for over 200 years, the global healthcare landscape has been anything but static. After receipt of your order, if applicable, you may be contacted by your local sales office. Wherever possible, therefore, compendial methods should be used to qualify reference standards. . A program to provide international biological standards and chemical reference substances is maintained by the World Health Organization, an agency of the United Nations. You dont have to waste time flipping through countless pages of standards. The WHO program is concerned with reference materials for antibiotics, biologicals, and chemotherapeutic agents. Reference standards can be segregated into two groups: chemical and nuclidic (1). Lot Number. Barcode App Compatibility Table II: Types of reference-standard material compared with recommended test. Harmonization Stage4 includes monographs or general chapters that have completed stages 1-4 of the pharmacopeial harmonization process resulting in approved USPNF text. Not all standards are created equal. The USP APP is intended to be a convenient tool for users. Unless a Reference Standard label states a specific potency or content, the Reference Standard is taken as being 100.0% pure for compendial purposes. No. The remaining 10% of impurities have to be identified and monitored through the life of the material.

We are a leading global distributor of high quality reference materials, which are essential for accurate analytical measurement and quality control, ensuring sound decisions are made based on reliable data. I.V. Scientists performing analytical testing use reference standards to determine quantitative (e.g., assay and impurity) as well as qualitative (e.g., identification tests) data, performance standards, and calibrators (e.g., melting point standards). The synthesis of the reference standard should be evaluated to predict and identify potential impurities from raw materials. More analytical tests must be performed, and the probability of the purity changing during the review period increases. The design of the long-term stress test depends on the intended storage condition. Our mobile app is one way were helping you build a strong foundation for a healthier world.

The relative-response factor approach requires additional development because the component needs to be isolated and the relative response factor must be determined. As a service, the USPC tests and distributes additional authenticated substances not currently required as USP or NF Reference Standards. 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. 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. Reference Standard In Stock Ready to ship $254.00 remove Add to Cart star Add to Favorites Quick View (-)-Epicatechin (50 mg) Catalog No. This raises the question, Which requirement should be met first: the qualification of the reference standard or its method validation? 1. Initial qualification and requalification. The US Pharmacopeia (USP) defines reference-standard materials as "highly characterized specimens of drug substances, excipients, reportable impurities, degradation products, compendial reagents, and performance calibrators" (2). If the amount of residual solvents present affects the purity, however, they should be evaluated at each requalification interval. In such instances, a specific reference standard is required for the cation, and a separate analytical method for quantitation may be needed. This may allow for an extended life of the reference standard if it is proven to be unstable for a long period of time at its anticipated storage condition.
