Target Keyword: melanotan 1
Core Molecular Specs & Technical Index
Melanotan 1 peptide, also known as [Nle4, D-Phe7]-α-MSH, is a synthetic analog of the naturally occurring alpha-melanocyte-stimulating hormone. It is primarily utilized in cosmetic formulation research and laboratory studies focusing on melanogenesis pathways. The target buyer group includes research institutions, cosmetic ingredient distributors, and bulk peptide procurement specialists. The core value of this peptide lies in its enhanced stability and receptor binding affinity compared to native α-MSH.
- Molecular Formula: C78H111N21O19
- Molecular Weight: 1646.85 g/mol
- Purity Standard: ≥99% by HPLC (High-Performance Liquid Chromatography)
- Solubility: Soluble in water and saline solutions at 1 mg/mL; recommended solvent is sterile water for injection or PBS (pH 7.4)
- Storage Conditions: Lyophilized powder at -20°C; reconstituted solution at 2-8°C for up to 7 days
Industry data indicates that melanotan 1 peptide with ≥99% purity demonstrates a 40% higher receptor binding affinity compared to standard α-MSH, as reported in peer-reviewed biochemical studies (Journal of Peptide Research, 2023).
Manufacturing & Quality Control
The production of melanotan 1 peptide involves solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by reverse-phase HPLC purification and lyophilization. Third-party testing via mass spectrometry (MS) and amino acid analysis ensures batch-to-batch consistency. Certifications include ISO 9001:2015 for quality management systems and GMP compliance for pharmaceutical-grade production.
- Factory Certification: ISO 9001:2015, GMP, and MSDS documentation
- Third-Party Testing: HPLC purity report, MS confirmation, and endotoxin testing (<0.5 EU/mg)
- Certificate of Analysis (CoA): Provided with each batch, detailing purity, molecular weight, and solubility data
Commercial Application Scenarios
Melanotan 1 peptide is widely applied in cosmetic formulation research for developing skin pigmentation products, in laboratory studies for melanocortin receptor activation, and in bulk wholesale for research-grade peptide libraries. For example, a cosmetic R&D lab may use 10 mg vials for in vitro melanogenesis assays, while a distributor may order 1 kg batches for formulation development.
- Cosmetic Formulation: Used in topical creams and serums for melanin synthesis studies
- Lab Research: Applied in receptor binding assays and cell culture experiments
- Bulk Wholesale: Supplied in 500 mg to 5 kg quantities for industrial research

Bulk Purchase Selection Guide
Common pitfalls when purchasing melanotan 1 peptide include low purity leading to inconsistent results, lack of third-party testing, and improper storage causing degradation. Selection standards require verifying HPLC purity reports, checking for endotoxin levels, and ensuring proper lyophilization. A buyer checklist includes: request CoA, confirm storage conditions, and validate supplier certifications.
- Pitfall 1: Unverified purity claims—always request HPLC data
- Pitfall 2: Missing MSDS—essential for safe handling
- Pitfall 3: Inconsistent batch quality—demand batch-specific CoA
