To consider the impact on the purity evaluation using area percent versus relative response factor, the following scenario may be considered. Something went wrong, please try again later. What would you do differently? FDA requires noncompendial reference standards to be "of the highest purity" and asks that reference standards validate analytical methods (1). The analytical procedures shown in Figure 1 are dependent on the evaluation of the development process. If the reference-standard program requires tests that are not captured in compendial methods (as is the case with organic impurities), then analytical test procedures must be developed and qualified.

Quantitation by area percent would not be appropriate in such cases. Product code: {{entry.product.displayPartCode ? Since some USP Reference Standards are standardized in terms of the corresponding International Standards, the relevant USP Units and the International Units of potency are generally identical. Initial qualification and requalification. To ascertain the degree to which an analytical method is deemed suitable for its intended use, the validation parameters set forth in ICH Q2(R1) Validation of Analytical Procedures (6) stipulates the following criteria: Not all parameters can be evaluated because a reference standard is required to perform quantitation. 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. All available USP Reference Standards (RS) can be purchased in the USP iStore. ICH also requires the reference material to be proven stable under the intended storage conditions for the intended use period (7).

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. 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. Chemical purity must be determined for both groups; nuclidic reference standards, however, also need to be evaluated for radionuclidic and radiochemical purity. For APIs, the material may start out as a lot of drug substance with sufficient purity to be designated as the reference-standard material, or it may require further purification. If possible, it is recommended the reference standard be in a salt-free state to reduce the characterization tests required.
