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). Rather, the impurities must be isolated and identified so that an appropriate reference standard can be used, or a relative response factor determined. The technique used to obtain this data will depend on the amount of impurities and related compounds present and the decomposition pathway of the reference-standard material. LGC will use your email address only for the purposes of providing the requested document. 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.

This level may be insufficient to affect overall purity results. Chemical purity must be determined for both groups; nuclidic reference standards, however, also need to be evaluated for radionuclidic and radiochemical purity. Applicants that use proprietary materials will find that primary standards are not typically available through compendial sources. These additional substances fall into three groups: (1) former USP and NF Reference Standards, not required in the current. The approach to determining the relative-response factor for each impurity is a more accurate process, but potential pitfalls should be considered.

While USPs public health mission has remained unchanged for over 200 years, the global healthcare landscape has been anything but static. Applying the molecular weight to the correction will not account for residual salt that may be produced during synthesis. The identity of the material should be confirmed with a "fingerprinting" technique such as fourier transform infrared spectroscopy (FTIR) to a library source or by elemental analysis to confirm the molecular formula. Compendial. The quantity of organic impurities present can be determined with high-performance liquid chromatography (HPLC) and ultra-violet (UV) detection.

For example, if the intended storage condition is 28 C then the reference standard should also be stored at 20 C as a contingency. Figure 1: Decision-tree for reference-standard qualification. To search for the SDS, you will just need the Product Name. Much of this information may be ascertained during the development of the drug substance. You dont have to waste time flipping through countless pages of standards. As a rule, an International Standard for a material of natural origin is discontinued once the substance responsible for its characteristic activity has been isolated, identified, and prepared in such form that it can be completely characterized by chemical and physical means. NIST provides a certificate of analysis (CoA) that includes purity information and an expiration date. Generally, Reference Standards should be stored in their original stoppered containers away from heat and protected from light.
