Contaminated Peptides

Meaning

Contaminated peptides refer to synthetic peptide compounds that contain impurities, unreacted starting materials, solvent residues, microbial byproducts, or unintended side-chain modifications resulting from suboptimal synthesis, purification, or storage processes. The presence of these non-target substances compromises the purity, potency, and safety of the peptide preparation, posing a substantial risk in both research and clinical application. This issue is a major concern in the unregulated market for research chemicals and custom-synthesized therapeutic agents.
