Kisspeptin is supplied as a laboratory research reference material intended strictly for in-vitro and laboratory research use only. This synthetic peptide is characterized by the molecular formula C63H83N17O14, a molecular weight of 1302.45 g/mol, and a monoisotopic mass of 1301.6305 Da, corresponding to CAS registry number 374675-21-5 and PubChem CID 25240297. The InChIKey RITKWYDZSSQNJI-INXYWQKQSA-N provides an unambiguous structural identifier for cross-referencing in cheminformatics databases and analytical workflows.
Structurally, Kisspeptin is a C-terminally amidated decapeptide with the one-letter sequence YNWNSFGLRF-NH2, comprising the residues Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe. The C-terminal amide, the internal tryptophan indole, and the aromatic tyrosine and phenylalanine side chains contribute distinct spectroscopic handles useful for UV monitoring at 214 nm and 280 nm during reversed-phase HPLC characterization, while the single arginine residue introduces a basic site relevant for ion-pairing chromatography and positive-mode ESI-MS detection.
The material is offered as a white to off-white lyophilized powder produced by synthetic manufacture, with purity established at not less than 98% by HPLC and confirmed against a lot-specific Certificate of Analysis available on request. Complementary identity and characterization data typically include mass spectrometric confirmation against the calculated monoisotopic mass, and the canonical SMILES string is provided for structural verification in laboratory information management systems. Formulators and analytical chemists can use these parameters as reference points when qualifying Kisspeptin in in-vitro assay development, method transfer, standard preparation, and comparability studies.
Published scientific literature has examined Kisspeptin in preclinical research contexts; PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding this material and provides no administration or dosing guidance. This material is not a drug, supplement, cosmetic, or food, and is not for human or veterinary use, injection, or ingestion.
