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

As a potent melanocortin receptor agonist, this peptide targets melanocortin receptors including MC3R and MC4R. It is widely adopted in preclinical laboratory research for the study of neuroendocrine signaling pathways and central nervous system related mechanisms. It serves as a reliable research reagent for investigating melanocortin biological functions.

Appearance: White or off-white lyophilized sterile powder. Quality Assurance: HPLC and mass spectrometry testing confirm the purity ≥99%. Batch-wise COA reports can be supplied upon request to support quality verification and batch traceability.

Packaging: Vacuum sealed in sterile glass vials. Storage Guidelines: Store unopened vials at -20°C, protected from light and moisture. Avoid repeated freeze-thaw cycles, which may degrade peptide bioactivity.
