Peptides are pivotal therapeutics that patients rely on to treat diabetes, obesity, cancer and more. Developers of these life-saving medicines face challenges interpreting regulations for biologics and small molecules that exclude peptides. USP supplies comprehensive peptide solutions including clear documentary standards with validated test methods, acceptance criteria and highly characterized API and impurity reference standards and materials. These tools help manufacturers minimize contaminants and build their control strategy. Clearly defined standards and guidance from USP help investigators and regulators save time and resources on the way to regulatory success.

USP Peptide Families
USP has assembled peptide families, consisting of peptide API Reference Standards, related impurity reference standards and Analytical Reference Materials. USP Reference Standards and materials can be used to develop and validate analytical methods, verify that compendial methods are fit for purpose in your laboratory, qualify equipment as well as control the quality of drug substance and product batches.
