Identity
Compound & chemical form
Match the product name, sequence where relevant, modifications and identifier to the requested specification. An abbreviated catalog name alone is not enough.

Quality & documentation
Evidence before assumptions.
A useful material record connects the compound, the analytical method and the exact lot. This guide explains what to review before purchase.
Documentation status
Know what is verified.
No verified supplier COAs, laboratory accreditations or lot-specific results have been provided for this catalog. We do not display invented purity percentages, laboratory partners or release signatures.
Use the criteria below to prepare your documentation request and evaluate the records for the material actually offered.
Prepare a documentation inquiryA document review guide
Four checks. One material record.
Method
What was measured
Identify the test method and reported units. Chromatographic area purity, peptide content and net fill amount describe different measurements.
Traceability
Lot & report details
Match the lot number on the material to the certificate. Review test date, issuing laboratory and any stated limitations.
Review
Your acceptance criteria
Compare the reported data with your institution’s requirements. Record unresolved discrepancies before accepting the material.
Keep the context
A COA is part of the record.
Combine analytical documentation with the material specification and safety data sheet.
Is HPLC purity the same as the amount of peptide in a vial?
No. Chromatographic purity describes a result under a defined method. It should not be treated as a direct measurement of total peptide content or vial fill amount.
Does a matching mass prove every aspect of identity?
No. A mass result is one piece of analytical evidence. Sequence, stereochemistry, chemical form and other relevant attributes may require additional characterization.
