Quality & Compliance

Peptide COA, HPLC, and MS documentation for buyer QA.

Ask sales for the batch-specific Certificate of Analysis matched to the offered or supplied lot. It records the tests performed, applicable specifications, and results for that lot; additional analytical documents can be scoped when required.

Released-batch lyophilized peptide vials with batch-traceability labels, photographed on PeptideXpo's QA inspection bench, every label corresponds to a batch-specific Certificate of Analysis.

Ask sales for the Certificate of Analysis corresponding to the lot offered or shipped. It records the work performed for that lot; raw data, stability, SDS, sequence verification, and expanded QA documentation can be scoped separately when required.

Certificate of Analysis

Per-batch record of the tests performed, applicable specifications, and reported results.

HPLC chromatogram

Available when recorded for the lot or included in the agreed documentation scope.

Mass-spec spectrum

Available when recorded for the lot or included in the agreed documentation scope.

Stability data

Product- and lot-specific evidence supplied when available or separately scoped.

Sequence report

LC-MS/MS sequence evidence when included in the agreed analytical scope.

Catalog PDF

Full SKU list with vial sizes, MOQ, and lead times. Updated quarterly.

Certifications & alignments

Built to international standards.

These labels are supplier-qualification topics, not a statement that every certificate applies to every product or site. Ask sales for the current certificate, legal entity, covered activities, issuer, and validity period before relying on a status in your file.
