The Melanotan 1 Analysis is a targeted laboratory test designed to confirm the identity, determine the amount, and assess the peptide purity of Melanotan 1 in lyophilised vials and raw active pharmaceutical ingredient (API) powders.For lyophilised samples, results are reported in milligrams per vial together with peptide purity. Raw API powders can be evaluated using purity in % (m/m) together with peptide purity.<h4>About Melanotan 1</h4>Melanotan 1 (MT-1), also known as afamelanotide, is a synthetic 13-amino-acid analogue of alpha-melanocyte-stimulating hormone (α-MSH). It acts as an agonist of the melanocortin-1 receptor (MC1R) and stimulates the production of eumelanin, the brown-black pigment involved in skin pigmentation and photoprotection.Melanotan 1 has been investigated extensively in studies of melanocortin signalling and pigmentation. Afamelanotide is also the active substance in the medicinal product Scenesse, authorised in the European Union for the prevention of phototoxicity in adults with erythropoietic protoporphyria.<h4>Key Features</h4><ul><li>Targeted identification and quantification of Melanotan 1</li><li>Determination of peptide purity</li><li>Suitable for lyophilised vials and raw API powders</li><li>Analysis by HPLC</li><li>Results for lyophilised samples reported in mg per vial and peptide purity</li><li>Alternative result format for raw API powders includes purity in % (m/m) and peptide purity</li><li>Minimum sample amount of one whole unopened vial with lyophilisate</li><li>Minimum sample amount of 30 mg for raw API powders</li><li>Average turnaround time of 7 business days</li></ul><h4>Analysis Parameters</h4><ul><li>Target compound: Melanotan 1</li><li>Other name: MT-1</li><li>CAS number: 75921-69-6</li><li>Molecular weight: 1647 Da</li><li>Sequence: Ac-DL-Ser-DL-Tyr-DL-Ser-DL-Nle-DL-Glu-DL-His-DL-Phe-DL-Arg-DL-Trp-Gly-DL-Lys-DL-Pro-DL-Val-NH2</li><li>Testing method: HPLC</li><li>Minimum amount of target compound for evaluation: Less than 1/20 of the usual dosage per vial</li><li>Result format for lyophilised samples: mg per vial and peptide purity</li><li>Result format for raw API powders: Purity in % (m/m) and peptide purity</li><li>Minimum sample amount for lyophilised samples: One whole unopened vial with lyophilisate</li><li>Minimum sample amount for raw API powders: 30 mg in a sealed glass vial to prevent the sample from absorbing moisture</li><li>Average turnaround time: 7 business days</li></ul><blockquote>Important Notice<ul><li>This analysis is specifically intended for Melanotan 1.
