Verify a batch
Enter the lot number printed on your vial. We resolve it against our third-party Certificate-of-Analysis index and return the real assay data for that exact batch - no sign-in, no guesswork.
How verification works
Every documented lot is traceable to an independent lab report. Verification just surfaces that record.
Read the lot
Find the lot or accession number printed on the vial label or its box, and type it above exactly as shown.
Match the record
We look the lot up in our COA index - the same index that powers the library - and pull the third-party assay for that batch.
Open the report
Confirm HPLC purity, mass-spec identity, net content and appearance, then open the original lab PDF inline.
