PT-141, also known as Bremelanotide, is a synthetic cyclic heptapeptide originating from α-melanocyte-stimulating hormone (α-MSH). Its CAS number is 189691-06-3 with a molecular weight of 1025.16 Da.

Classified as a melanocortin receptor agonist, this peptide is widely used in preclinical laboratory research to study binding interactions with MC3R and MC4R, neuroendocrine signaling, and central nervous system related studies. It serves as a valuable research tool for exploring the biological mechanisms of the melanocortin pathway.

Appearance: White to pale off-white sterile lyophilized powder. Quality Control: HPLC and mass spectrometry tests verify purity ≥99%. COA documents for each batch can be provided upon request for quality validation and complete batch traceability.

Packaging: Vacuum sealed in sterile glass vials. Storage Recommendations: Store unopened vials at -20°C away from light and moisture. Avoid repeated freeze-thaw cycles, as they will reduce the biological activity of the peptide.
