Product Overview

PT-141 is a synthetic peptide research compound developed for advanced laboratory investigations involving melanocortin receptor biology, peptide receptor signalling and intracellular molecular communication. Also known in scientific literature as Bremelanotide, PT-141 has attracted considerable research interest because of its interaction with melanocortin receptor systems and its value in experimental models examining receptor-mediated peptide signalling under carefully controlled laboratory conditions. This preparation contains 10 mg of lyophilized PT-141 supplied in a sealed research vial. Independent analytical testing measured an assay content of 11.91 mg for this production batch. Chromatographic analysis confirmed 99.7 percent purity, while identity was independently evaluated through FTIR spectrum analysis, retention time confirmation and molecular ion mass identification. Microbiological testing reported 0 CFU/g for both total aerobic microbial count and total yeast and mold count, while bacterial endotoxin analysis returned a result of 0.029 EU/mg. Comprehensive elemental impurity screening additionally reported arsenic, cadmium, mercury, lead, nickel, vanadium and cobalt below 0.001 ppm. With its highly defined molecular identity, reproducible analytical characteristics and comprehensive third-party verification, PT-141 provides researchers with a well-characterised peptide material suitable for advanced receptor biology and controlled in vitro laboratory investigations.  

Peptide Overview

PT-141 is a synthetic cyclic peptide research compound commonly utilised in laboratory investigations involving melanocortin receptor biology, peptide pharmacology and receptor-mediated intracellular signalling. PT-141 belongs to the melanocortin peptide research field and is structurally related to compounds developed from alpha-melanocyte-stimulating hormone research. Researchers employ PT-141 in controlled experimental models designed to investigate melanocortin receptor interactions, receptor-mediated signalling pathways and complex biochemical communication systems. Its defined molecular structure, reproducible analytical characteristics and established presence within melanocortin research have made PT-141 a recognised compound within modern experimental peptide science. Today, PT-141 continues to appear throughout scientific research involving peptide pharmacology, receptor biology, molecular signalling and biochemical regulatory mechanisms.  

Historical Background and Scientific Context

Melanocortin peptides have been investigated extensively within molecular biology and peptide pharmacology because of their interactions with a family of G-protein-coupled melanocortin receptors. Advances in synthetic peptide engineering enabled researchers to develop increasingly selective peptide compounds for studying these receptor systems and the intracellular signalling pathways associated with receptor activation. PT-141 emerged from this broader field of melanocortin peptide research and has subsequently become an established experimental compound for investigating receptor-mediated molecular communication. Modern analytical technologies including ultra-high-performance liquid chromatography, FTIR identification and mass spectrometry have significantly improved the ability to verify peptide identity, purity and manufacturing consistency across laboratory-grade research compounds. Today, PT-141 remains part of the expanding field of investigational peptides utilised for scientific research and controlled in vitro experimentation.
