KPV

KPV is supplied as a laboratory research reference material intended strictly for in-vitro and laboratory research use only. This synthetic tripeptide corresponds to the C-terminal fragment of the alpha-melanocyte-related melanocortin sequence, comprising L-lysine, L-proline, and L-valine in the linear order Lys-Pro-Val (three residues, N-terminal free amine on lysine, C-terminal free carboxylate on valine). The compound is catalogued under CAS 67727-97-3 and PubChem CID 125672, with the InChIKey YSPZCHGIWAQVKQ-AVGNSLFASA-N and the isomeric SMILES CC(C)C(C(=O)O)NC(=O)C1CCCN1C(=O)C(CCCCN)N providing unambiguous structural descriptors for cheminformatics workflows and database cross-referencing.

The molecular formula C16H30N4O4 corresponds to an average molecular weight of 342.43 g/mol and a monoisotopic mass of 342.2267 Da, values useful for calibrating LC-MS and high-resolution mass spectrometry methods when KPV is used as an analytical standard. The central proline residue introduces a conformational constraint through its cyclic secondary amine, while the lysine side chain contributes a primary epsilon-amino group (a basic, protonatable site relevant to ion-exchange behavior and reversed-phase retention) and valine supplies a hydrophobic beta-branched terminus. This combination gives KPV a distinctive chromatographic and mass-spectral fingerprint suitable for identity confirmation, method development, and reference peak assignment.

Physically, KPV is provided as a white to off-white lyophilized powder of synthetic origin, with purity established at not less than 98% by HPLC and documented on a lot-specific Certificate of Analysis available on request. The lyophilized format supports accurate gravimetric handling in analytical laboratories and long-term stability under appropriate cold, desiccated storage conditions typical for short peptide reference materials.

Published scientific literature has examined KPV in preclinical, in-vitro, and biochemical research contexts, and it is frequently cited as a melanocortin-derived tripeptide of interest in structural and mechanistic studies. PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding this material and provides no administration or dosing guidance. This KPV research reference material is not a drug, supplement, cosmetic, or food, and is not intended for human or veterinary use, injection, or ingestion. It is offered solely to qualified researchers and institutional laboratories for characterization, analytical, and in-vitro reference applications.
