Each COA documents identity and purity testing for the current batch.
Check that the product name and batch/lot number match the label on your vial, then confirm the purity figure and the test date. Identity is established by mass spectrometry — the observed mass should match the theoretical mass for that sequence.
Viewing a COA here shows the certificate for the current batch. If you need the certificate for a specific lot you already have, email [email protected] with the lot number on your vial and we'll send that exact document.
