{"product_id":"melanotan-2","title":"Melanotan 2","description":"Melanotan 2 (MT-2) is a synthetic cyclic heptapeptide — a ring-shaped chain of seven amino acids — and an analog of alpha-melanocyte-stimulating hormone (alpha-MSH). It has the molecular formula C50H69N15O9, a molecular weight of 1024.20 g\/mol, and a CAS number of 121062-08-6. Its defining structural feature is a lactam bridge, an internal bond that closes the amino acid chain into a ring, making it more compact and enzyme-resistant than linear peptides. First synthesized in the 1990s, MT-2 is classified as a non-selective melanocortin receptor agonist, meaning it is structurally compatible with multiple receptor subtypes (MC1R, MC3R, MC4R, MC5R). Supplied as a white to off-white lyophilized powder, it is soluble in water and dilute acetic acid.
