Short answer
Use this seven-point checklist before accepting a peptide lot into laboratory inventory: compound name, lot match, test date, HPLC method, purity result, identity confirmation, and RUO-only intended use.
How to use this checklist
Print or save this page for receiving and QA workflows. Each incoming peptide vial should be matched to its lot-specific COA before the material enters active assays.
7-point COA verification checklist
- Compound name matches the PO and vial label — The COA compound field equals the catalogue name and SKU ordered.
- Lot number on vial equals lot on COA — Batch-specific documentation must tie to the physical vial — not a generic catalogue COA.
- Test date is present and recent enough for your SOP — Document when the lot was tested relative to your receiving date.
- HPLC method and purity are reported — Method (e.g. RP-HPLC C18) and numeric purity (e.g. ≥98%) should be explicit.
- Identity confirmation is reported — LC-MS, ESI-MS, or MALDI-TOF with expected mass within tolerance.
- Vial size / quantity matches the COA — Especially important for multi-size SKUs and blends.
- RUO-only intended use is documented — Material is qualified laboratory research — not for human or veterinary use.

What if the COA is missing identity data?
Treat as incomplete documentation. Request lot-specific identity testing records before using the material in critical assays.
