What PT-141 Peptide Powder Is
PT-141 Peptide Powder (Bremelanotide) is a synthetic heptapeptide with the sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH. Its chemical structure is derived from endogenous α-melanocyte-stimulating hormone (α-MSH). As a second-generation melanocortin receptor agonist, PT-141 has attracted significant research interest due to its unique mechanism of action within the central nervous system. Unlike traditional therapies that rely on the nitric oxide pathway, PT-141 activates melanocortin receptor subtypes MC3R and MC4R in the brain

Chemical Characteristics and Physical Properties
PT-141 peptide is a cyclic heptapeptide with the molecular formula C₅₀H₆₈N₁₄O₁₀ and a molecular weight of 1025.19 g/mol. It contains the non-natural amino acid Nle (Norleucine) and D-phenylalanine; these modifications enhance its stability against enzymatic degradation and increase its affinity for specific melanocortin receptors. Its CAS number is 189691-06-3, a unique and critical identifier. The product is typically supplied as a white to off-white lyophilized powder with high purity. Its cyclic structure is central to its bioactivity and resistance to proteolytic hydrolysis. Regarding solubility, PT-141 peptide powder is soluble in water, though solubility may be limited in distilled or sterile water for injection; it generally dissolves better in 1% acetic acid solution or physiological saline (0.9% NaCl), forming a clear solution. Strong acidic or alkaline solvents should be avoided to prevent peptide bond cleavage. For storage, the primary powder should be kept dry, protected from light, and at -20°C or lower to ensure long-term stability. Reconstituted solutions should be refrigerated at 2-8°C and are recommended for short-term use (e.g., within a week), or aliquoted and frozen, avoiding repeated freeze-thaw cycles.
Market Outlook and Summary
PT-141 peptide powder, as a signature tool compound in melanocortin research, enjoys consistent and stable demand. As research in neuroscience and sexual medicine deepens, particularly in exploring gender differences and the role of the central nervous system in behavioral regulation, the scientific value of the PT-141 peptide will become even more prominent.
