Clinical Scorecard: The New Reality of Peptide Analysis

At a Glance

Key Highlights

• Peptide therapeutics require deep structural characterization beyond simple purity metrics.
• GLP-1 analogs illustrate the limitations of small-molecule analytical assumptions.
• Orthogonal analytics like HRAM MS and UHPLC are essential for resolving peptide variants.
• Detection of low-concentration impurities is critical for maintaining biological activity. [Remove unless sourced]
• Workflows must balance high-end characterization with practical deployability in QC.
