Revisions are presented three times a year in the USP-NF as Issues 1, 2, and 3, and as monthly Accelerated Revisions on the USP website. In such instances, a specific reference standard is required for the cation, and a separate analytical method for quantitation may be needed. Approval of AVRs for use in a monograph is the decision of the Expert Committee that approves the specific monograph. Materials can be developed or purchased from chemical-supply companies for use as in-house secondary reference standards even when compendial reference standards are available. In addition, this type of standard reduces the degree of systematic and random error from the combined analytical tests. 20, 2008. Labs, Inc. 1985 - 2023 I.V. Reference-standard materials can be broadly categorized as such: The level of characterization depends on the intended use of the reference standard. 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. Each of these factors must be considered in the development of a comprehensive reference-standard material program.

Once identity has been established and confirmed, the quality of the material must be ascertained. ICH, Q3A(R2) Impurities in New Drug Substances (Geneva, Switzerland), Oct. 25, 2006. To consider the impact on the purity evaluation using area percent versus relative response factor, the following scenario may be considered. Typically, organic impurities are identified and confirmed using liquid chromatographymass spectrometry (LGMS); nuclear magnetic resonance (NMR) and inductively coupled plasma/mass spectrometry (ICPMS) are used for inorganic impurities; and gas chromatography/mass spectrometry (LCMS) is used for residual solvents. 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). We establish primary standards for helping to ensure quality in pharmaceutical development and manufacturing. 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. As we work through these updates, you may experience some temporary discrepancies in information.

Initial characterization of the reference standard should include a full suite of analytical tests. It should also be determined whether enantiomeric or polymorphic forms exist. Reference standards that contain a high percentage of organic volatile impurities may experience purity changes over time as the solvents evaporate. Elemental analysis, titration, GC, or LC can be used for purity determination. Public pharmacopeial standards for chemical and biological drug substances, dosage forms, compounded preparations, excipients, medical devices, and dietary supplements. Residual solvents. Chemical purity must be determined for both groups; nuclidic reference standards, however, also need to be evaluated for radionuclidic and radiochemical purity. Submitted: Mar.
