Description

General description

Sodium trifluoroacetate (TFA) is a commonly encountered residual reagent or counter-ion in peptide synthesis and purification. It is often present due to the use of trifluoroacetic acid in cleavage and purification steps. The USP standard supports the identification and quantification of TFA in peptide active pharmaceutical ingredients (APIs) and formulations.

The USP biologics peptides category encompasses a diverse range of therapeutic peptides that are essential in managing various medical conditions. These peptides, typically consisting of amino acid sequences of 40 residues or less, are critical for the development of high-quality medicines. The USP provides comprehensive standards, reference materials, and analytical procedures to ensure the identity, quality, purity, and consistency of peptide therapeutics throughout their lifecycle.

The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
