KPV is a synthetic tripeptide, the C-terminal fragment of alpha-MSH, supplied as a lyophilized powder at 10 mg per vial. Purity is ≥99% by HPLC, with identity confirmed by mass spectrometry, so the vial arrives with its analytical record already established. Price is $64.99 CAD per vial, sold for research use only.
Why the ≥99% HPLC figure and CAS 67727-97-3 matter
- Purity with its method: Purity is stated as ≥99% by HPLC, not as an unqualified number. The method is named on the certificate of analysis so the figure can be checked against a lot.
- Identity confirmation: Mass spectrometry confirms identity alongside the HPLC assay. Two methods, one lot record.
- Fixed identity facts: Molecular formula C16H30N4O4, molecular weight 342.4 g/mol, CAS 67727-97-3. These can be entered directly into a reagent register.
- One quantity: This item is offered as a single vial containing 10 mg of lyophilized powder. No other fill size is listed for KPV.
- Packed for transit: The vial ships at ambient temperature with desiccant, inside an insulated mailer from Richmond, BC.

Who the 10 mg fill suits
The 10 mg vial fits an in-vitro programme that needs a single tripeptide lot with documented purity, and it fits a purchasing officer who must attach a certificate of analysis to a requisition before the reagent enters the inventory. A laboratory running several parallel assays would order multiple vials, since only the 10 mg fill is listed here. Note that the 0.05 kg figure is the packed courier weight, not the net content.
Lyophilized powder: store sealed at -20 °C, protected from light and moisture. Every lot ships with a downloadable lot-specific certificate of analysis stating identity, purity and test method. For laboratory research use only. Not for human or veterinary use.
