Quality & trust
Certificates of analysis
American Peptide Research publishes batch-level certificates of analysis so researchers can verify identity and purity before experiments begin—not after results fail to reproduce.
Identity confirmation
LC-MS molecular weight verification against theoretical mass for the labeled sequence.
Purity profiling
HPLC peak area analysis with method and reference standard documented on each COA.
Batch traceability
Unique lot ID assigned at lyophilization and linked to fulfillment and customer COA access.
Endotoxin screening
LAL or equivalent testing reported where applicable to the compound class.
Release review
Internal QC sign-off before any lot is approved for catalog listing or shipment.
Sample COA viewer
Interactive COA viewer and batch lookup are coming soon. Authenticated customers can already access COAs for shipped batches from product and order pages.
For laboratory research use only. COAs support quality verification workflows and do not constitute medical or clinical documentation.
