Quality & documentation

Every batch is released against a written specification, with results on the certificate of analysis.

What each batch includes

• Certificate of analysis (COA) — the core release document is a batch-specific COA listing methods and results.
• HPLC chromatogram — purity determination, method stated on the document.
• MS identity confirmation — molecular-weight verification.
• Safety documentation (SDS) — available on request.

How to read a peptide COA — a short guide for buyers

Two numbers matter most and they are not the same: analytical purity (what the HPLC method reports for the main peak) and peptide content (the fraction of the material that is the peptide itself, with the remainder being counterions, residual solvents and water). A material with 99% HPLC purity may still carry a lower net peptide content — both values belong in a complete COA. Ask any supplier which methods and reference standards were used.

Certifications

Quality system details and applicable certifications are confirmed during supplier qualification. We state credentials only with their exact scope, issuer and validity.

Custom projects

Custom synthesis projects are reviewed for technical feasibility, intended use and destination-market requirements before quotation.
