A Certificate of Analysis (COA) is a batch record that helps a laboratory review the identity and analytical quality of a research material. It should be read together with the vial lot number and the product specification.
What to match first
Start with the product name, catalog reference, CAS number where applicable, lot number, and report date. The lot shown on the COA should match the lot supplied with the vial. A generic certificate that cannot be tied to the received lot is less useful for traceability.
Purity is one result, not the whole record
HPLC purity, identity confirmation, measured content, residual moisture, and related analytical values answer different questions. Review the method and result for each field instead of treating one percentage as proof of every characteristic.
Research catalog examples
Our Peptide Research Library links the catalog to product pages for TIRZ, SEMA, RETA, CagriSema, BPC-157 + TB-500, and other research materials. Each page states the supplied form, available formats, research context, and how to request batch documentation.
Storage and handling records
Keep the vial sealed, dry, protected from light, and within the storage conditions stated on the label and applicable documentation. Preparation, assay design, and disposal should follow the qualified laboratory's established procedures.
Request a batch record
To request a COA, email the product name and lot information before placing a documentation-sensitive order. This helps the team match the request to the correct batch record.

Frequently Asked Questions
Does a COA prove safety or approval?
No. A COA reports selected results for a specific lot; it is not FDA approval and does not establish clinical safety or efficacy.
Should the lot number match the vial?
Yes. The lot on the certificate should match the material being reviewed so the record is traceable.
Does HPLC alone confirm identity?
No. HPLC purity and identity testing answer different questions; review the listed methods together.
