Peptides and its Impurities

Peptides are naturally occurring biological macromolecules formed by the linear arrangement of two or more amino acids linked together by peptide bonds. It can be used as biomarkers for disease detection and diagnosis. Reference standards of Peptides API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
