Peptides Standards

Peptide pharmaceuticals are valuable therapies that are highly selective, have low toxicity, and are relatively economical to manufacture. Peptides can be manufactured synthetically (using solid-phase peptide synthesis (SPPS) or by employing recombinant DNA technology.

The United States Pharmacopeia (USP) publishes official monographs and general chapters that provide quality standards for drug substances and products across the world. These documentary standards focus on the quality attributes of identity, purity, safety, and potency of the drug products regulated by authorities that enforce these standards. Peptide-related USP Reference Standards are closely tied to our documentary standards and are directly associated with official monographs published in the USP–NF. These highly characterized physical specimens are used in testing by pharmaceutical and related industries to help ensure the identity, strength, quality and purity of peptide-based medicines.

Ensuring the identity, quality, purity, and consistency of medication is fundamental to protecting public health. Peptide-related USP documentary standards can give drug manufacturers confidence in developing high-quality medicines. Peptide-related USP Reference Standards are closely tied to our documentary standards. Based directly on official monographs published in the USP–NF, these highly characterized physical specimens are used in testing by pharmaceutical and related industries to help ensure the identity, strength, quality and purity of peptide-based medicine

Below is a current list of Peptide-related USP official standards published in the USP-NF, with related USP Reference Standards and Associated Impurity Reference Standards.

Support development of new peptide standards

USP continues to increase the number of peptide-related monographs in the United States Pharmacopeia-National Formulary (USP–NF). Included in the table below are some of the monographs and general chapters currently under development or in revision (labeled with an *). A complete listing can be found in USP’s Pharmacopeial Forum (PF), a free bimonthly online journal where proposed monographs and general chapters are published for public review and comment before becoming official. To learn more, visit https://www.uspnf.com/ pharmacopeial-forum

In addition, your participation in our standards-setting process is vital to the development of relevant USP–NF monographs. USP seeks sponsors as well as analytical methods to help develop the following monographs:

  • Ganirelix
  • Icatibant
  • Liraglutide

Learn how you can donate material or methods by visiting our biologics standards engagement page or by contacting us at uspbiologics@usp.org.
