KPV is the tripeptide Lys-Pro-Val and corresponds to the C-terminal tripeptide of α-melanocyte-stimulating hormone. The short name does not specify salt, terminal form, water or peptide-equivalent content.
Evidence at a glance
- The catalog free-peptide record uses formula C16H30N4O4 and molecular weight 342.44 g/mol.
- KPV acetate and free-base KPV are distinct calculation records.
- The 2026 FDA compounding materials separately names KPV acetate and KPV free base, reinforcing the need to state form.
Identity record
For a three-residue peptide, intact mass is useful but not sufficient. A related fragment, stereoisomer or counterion contribution may require orthogonal methods and a well-characterized reference.
Analytical and evidence boundary
Area-percent purity is not a direct assay of peptide-equivalent content. Water, acetate and non-UV-active components can affect the weighed amount without appearing as peptide peaks at a selected wavelength.
Do not turn the α-MSH relationship into claims about pigmentation, inflammation or tissue repair. Each endpoint requires a directly matched study and model.
Editorial rule
State the exact material, form, model or population and endpoint supported by the cited record. Do not convert mechanistic plausibility, an animal result, an official finished-drug label or an analytical test into a claim about an unrelated catalog lot.
