Peptide Purity

Meaning

Peptide purity is a critical quality metric in clinical peptide synthesis, defined as the percentage of the final product that is the desired, correctly structured amino acid sequence, excluding all impurities, such as truncated sequences, oxidized forms, or residual solvents. A high purity level, typically exceeding 98%, is essential to ensure the therapeutic efficacy, predictable pharmacokinetics, and patient safety of injectable peptide compounds. Clinicians must verify purity to guarantee the intended biological effect is achieved without unintended consequences from contaminants.
