Batch Verification Portal

Look Up a Lot Number

Enter the lot number printed on your vial label. Each published record shows the batch’s HPLC purity result, mass-spectrometry identity confirmation, test date, analytical method, and testing laboratory.

Records are published only after a batch clears third-party testing. If a lot is not yet listed, it may still be in or awaiting release — contact QA with your lot number and we will respond within one business day.

What Every Record Contains

• HPLC purity — reverse-phase high-performance liquid chromatography for the batch, reported as percent purity, with the chromatogram on file.
• Mass-spectrometry identity — molecular-ion confirmation that the material in the vial matches the compound on the label.
• Method & traceability — test date, analytical method, testing laboratory, and a downloadable signed PDF certificate.

How Verification Works

1. Each batch is sampled on release and sent to an independent analytical laboratory.
2. The laboratory runs HPLC for purity and mass spectrometry for identity; the signed certificate is archived against the lot number.
3. When the batch clears, its record is published on this page — permanent, indexed, and checkable against the label on your vial.
4. Any discrepancy between a published record and your vial label is handled under our resolution policy — contact us with the lot number.
