Melanotan 1
Melanotan 1 (afamelanotide) is a synthetic linear peptide composed of 13 amino acids, designed as an analog of the naturally occurring alpha-melanocyte-stimulating hormone (alpha-MSH). It has the molecular formula C78H111N21O19, a molecular weight of 1646.85 g/mol, and a CAS number of 75921-69-6. First synthesized in the 1980s, Melanotan 1 was engineered by modifying the native alpha-MSH sequence to increase chemical stability and resistance to enzymatic degradation. It is classified as a melanocortin receptor agonist with high selectivity for the MC1R receptor subtype. Supplied as a white to off-white lyophilized powder, it dissolves readily in water. This product is for research purposes only.

+ ENDO PASSEDOverview
Melanotan 1, also known as afamelanotide, is a synthetic analog of alpha-melanocyte-stimulating hormone (alpha-MSH). It is a linear peptide composed of 13 amino acids with the molecular formula C78H111N21O19 and a molecular weight of 1646.85 g/mol. Its CAS registry number is 75921-69-6. The “linear” designation means the amino acid chain is arranged in a straight sequence without any internal ring or bridge structures, in contrast to its cyclic counterpart Melanotan 2.
Melanotan 1 was first synthesized in the 1980s by modifying the natural alpha-MSH sequence to create a more chemically stable version with greater resistance to enzymatic degradation. It is classified as a melanocortin receptor agonist with high selectivity for the MC1R (melanocortin-1 receptor) subtype. The compound is supplied as a white to off-white lyophilized powder that dissolves readily in water.
