Generally, Reference Standards should be stored in their original stoppered containers away from heat and protected from light. Foods Download the list as: EXCEL | PDF Pharmaceutical Analytical Impurities 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. The suitability of a USP Reference Standard for noncompendial application is left up to the user. Consider a reference standard that is 90% pure. The material should be stored in a secure environment with controlled access and distribution. Then consider a reference standard with a purity of 99.9%, which has less need for additional characterization and potential degradation. 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. Many Pharmacopeial tests and assays are based on comparison of a test specimen with a USP Reference Standard. 2023 MJH Life Sciences and Pharmaceutical Technology.

Chemical purity must be determined for both groups; nuclidic reference standards, however, also need to be evaluated for radionuclidic and radiochemical purity. 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. Much of this information may be ascertained during the development of the drug substance. USPs Medicine Supply Map (MSM) is a graph-based predictive data model that generates insights into the upstream medicine supply chain. This requirement is meant to ensure that the product being evaluated is accurately tested to determine the amount of API present and to classify and identify related substances, process-related impurities, and degradation products. Different types of reference-standard materials and the qualification tests recommended are presented in Table II. In this scenario, it is recommended that during development, the reference standard be assessed after 3 months at the intended storage condition and at an accelerated storage condition. Impurities within acetone, a Class 3 solvent, for example, are permissible up to 5000 ppm or 0.5%, according to USP and ICH guidelines (5).
