PT-141
Bremelanotide
Melanocortin receptor agonist. Cyclic heptapeptide. PT-141 is a short melanocortin agonist presented as a freeze-dried solid with amber-glass packaging and argon-flushed headspace.
Synthesis uses Fmoc solid-phase chemistry with HBTU activation; crude peptide is precipitated in cold ether and polished by reverse-phase HPLC until purity floors at 99%. Every lot leaves the bench with ESI-TOF, LAL endotoxin, and residual-solvent data attached.
Lyophilised material is stable frozen at −20 °C. In aqueous solution, HPLC purity holds refrigerated for roughly two weeks; single-thaw only, no repeated freeze-thaw cycles.
