Core analytical requirements include: Primary structure confirmation : Amino acid sequencing and composition analysis Molecular weight determination : High-resolution mass spectrometry Purity assessment : HPLC with UV detection and mass spectrometry Impurity profiling : Related substances, residual solvents, and heavy metals Secondary structure analysis : Circular dichroism or NMR spectroscopy (for certain peptides) Potency determination : Bioassays or binding studies The FDAs guidance documents, particularly for synthetic peptides and peptide-based biologics, emphasize that characterization must be fit-for-purposemeaning the analytical strategy should match the peptides complexity, intended use, and stage of development
