Short-term (forced degradation) and long-term (evaluation under accelerated conditions) stress testing, therefore, should be evaluated during development. Table I presents recommended qualification parameters compared with reference-standard material type. - United States Pharmacopeia (USP) Reference Standard; CAS Number: 427-49-6; Synonyms: 2--2-; find USP-1296042 MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich These additional substances fall into three groups: (1) former USP and NF Reference Standards, not required in the current. FDA requires noncompendial reference standards to be "of the highest purity" and asks that reference standards validate analytical methods (1). Thus, it is unnecessary to name repetitively the revised Reference Standards in the general index to the Supplement. Barcode App Compatibility 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. Reference Standards currently labeled as NF Reference Standards will eventually all be designated and labeled as USP Reference Standards pursuant to the consolidation of USP and NF within the USPC as of January 2, 1975.

Requalification at subsequent points may include a reduced suite of analysis, depending on initial results. 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. Another reason to limit impurities is demonstrated in the following scenario. Consider a reference standard that is 90% pure. 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.

Heterogeneous substances, of natural origin, also are designated Reference Standards where needed. 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. Rather, the impurities must be isolated and identified so that an appropriate reference standard can be used, or a relative response factor determined. ICH, Q1A(R2) Stability Testing of New Drug Substances and Products (Geneva, Switzerland), Feb. 6, 2003.
