Why the ≥99% HPLC figure is stated per lot

Purity here is paired with its method: ≥99% by HPLC, with identity confirmed by mass spectrometry. The certificate of analysis is lot-specific, so the figure on the document matches the vial in hand rather than a general product claim. Purchasing officers who need documentation on file can download it for the lot they received.

The identity facts are fixed and checkable. Molecular formula C32H49N9O5, molecular weight 639.8 g/mol, CAS 736992-21-5. Those three values let a laboratory confirm it is comparing the same tetrapeptide across suppliers before committing to a $149.99 CAD line item.

Good to know before you order

Ordering is limited to laboratories and qualified researchers. Every lot is traceable to its downloadable certificate of analysis. For laboratory research use only. Not for human or veterinary use.

One quantity

The vial contains 50 mg of lyophilized powder, and this listing is sold as a single vial in that quantity only.

Storage on arrival

The lyophilized powder should be stored sealed at -20 °C, protected from light and moisture, so freezer space should be confirmed before the order is placed.

How it ships in Canada

Orders leave Richmond, BC in an insulated mailer with desiccant and travel at ambient temperature.
