Every lot shipped from Bench 01 is paired with a sealed third-party Certificate of Analysis documenting identity, purity, and (where applicable) endotoxin level. COAs are retained for a minimum of seven years.
Identity
LC-MS confirmation
Liquid chromatography-mass spectrometry trace confirming molecular weight against the theoretical mass of the named compound.
Purity
HPLC chromatogram
High-performance liquid chromatography trace with integrated peak area, reported as percent of total UV absorbance at 220 nm. Minimum 99.0% to pass.
Safety
Endotoxin assay
LAL (Limulus amebocyte lysate) endotoxin quantification for in-vitro cell-culture applications. Reported in EU/mg.
Requesting a COA
A COA is included automatically with every shipment. To retrieve a COA for a previously-purchased lot, please contact us with the lot number printed on your vial label and the order reference number. We will return the original signed PDF within one business day.
Note: this storefront is a research-supplier development sandbox. Live COA delivery uses the production COA pipeline at yourpeptidebrand.com — this site exists for engineering and QA validation only.
