PubChem identifies KPV as L-lysyl-L-prolyl-L-valine with the condensed structure H-Lys-Pro-Val-OH and independently confirms its sequence, formula, molecular weight, and CAS number.

Research Applications

Analytical characterization using HPLC, UPLC, and LC-MS workflows

Evaluation of short-peptide identity and molecular integrity

Structure-activity analysis of α-MSH-derived peptide fragments

Investigation of peptide-mediated molecular interactions in controlled in vitro systems

Comparative assessment of KPV and related melanocortin-derived peptide sequences

Peptide purity and molecular-weight confirmation

Evaluation of concentration-dependent molecular responses under defined experimental conditions

Comparative characterization of free-acid and counterion-containing KPV preparations

Stability profiling under controlled temperature, pH, buffer, and storage conditions

Quality Documentation

A batch-specific Certificate of Analysis and applicable analytical documentation should be available for each lot. Verify peptide identity, sequence, purity, molecular weight, counterion status, formulation details, and batch information against the records supplied with the individual product.

The molecular formula, molecular weight, and CAS number listed above correspond to free KPV, H-Lys-Pro-Val-OH. KPV acetate is a distinct preparation. PubChem lists the 1:1 acetate material separately as C₁₈H₃₄N₄O₆ with a molecular weight of approximately 402.5 g/mol and CAS 2828433-34-5. Free KPV and KPV acetate should therefore not be treated as analytically identical materials.

Batch-specific HPLC and mass-spectrometric documentation should be used as the final reference for product specifications.
