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.

Sample batch documents

A recent certificate of analysis is provided with your inquiry; full document packages are confirmed per batch and per order.

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.

Documentation FAQ

What is your minimum order quantity?

MOQ depends on the peptide and specification. Pilot quantities for qualification are supported before commercial-scale supply. Send your target grade and annual volume through the RFQ form; the assigned contact confirms the response window when acknowledging the request.

What documents come with each batch?

Each batch ships with a batch-specific certificate of analysis. HPLC chromatograms, mass-spectrometry identity data and safety documentation are available on request for qualified inquiries. Document packages are confirmed per order.

Do you offer custom synthesis and OEM?

Yes. Custom peptide synthesis from sequence, counterion exchange, lyophilization and OEM packaging are supported for qualified B2B projects. Projects are reviewed for intended use and destination-market requirements.
