In analytical chemistry peptides, laboratories typically review data to confirm identity, purity, and suitability for the intended research use. A complete analytical package should support the product description and provide enough detail for internal review.
Key items to check
- Identity evidence such as mass spectrometry results that match the expected molecular mass.
- Purity data from HPLC, including the reported percentage and the chromatogram.
- Method details so the testing conditions can be evaluated for relevance.
- Batch-specific documentation that ties results to the exact lot received.
- COA consistency between the label, certificate of analysis, and test reports.
It is also useful to note whether the report identifies impurities, solvents, or truncation products, since these can affect interpretation in research settings. If any result is unclear, laboratories should request clarification before using the material.
Reminder: research peptides are intended for laboratory research only and are not intended for human consumption.
