Quick Answer
A peptide COA should list batch number, HPLC purity percentage, mass spectrometry identity confirmation, and testing date—generic template COAs without batch data are inadequate for research procurement.
What is a certificate of analysis (COA)?
A COA is the analytical record tying a specific manufacturing batch to measured quality attributes—primarily purity and identity—for a research peptide.
What should every peptide COA include?
- Date of analysis
How do you verify HPLC results?
Confirm the reported purity peak area, method reference, and that the batch ID on the COA matches your shipment. Purity without identity data is incomplete.
What does mass spectrometry confirm?
MS verifies the compound’s mass/charge profile aligns with the ordered sequence salt form—critical to detect mislabeled or degraded material.
What are red flags on vendor COAs?
- Purity claimed without chromatogram reference
How does COA review fit procurement SOPs?
Institutional labs archive COAs in ELN/LIMS systems alongside study IDs. Link each experiment to the exact batch consumed.
Where to source COA-backed peptides
Browse the research shop or flagship SKUs such as Regeno Blend with documented testing.
