High-purity lyophilized APIs, diagnostic intermediates, and custom pharmaceutical-grade compounds for global enterprise distribution.
An authoritative analysis of global demand drivers, structural synthesis benchmarks, and enterprise supply chain optimization for Melanotan I 10mg OEM manufacturing.
Information Gain Key Metric: Global demand for synthetic α-MSH analogues (Melanotan I / Afamelanotide, CAS 75921-69-6) is experiencing a CAGR of 11.4% across life science research institutes, clinical trials, and therapeutic applications. OEM procurement demands strict control over peptide impurity profiles, trifluoroacetic acid (TFA) counterion exchange, and cold-chain stability.
Melanotan I (Afamelanotide) is a synthetic, linear peptide analogue of naturally occurring alpha-melanocyte-stimulating hormone (α-MSH). Chemically designated as [Nle4, D-Phe7]-α-MSH, it possesses the amino acid sequence: Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2.
Unlike non-selective agonist Melanotan II (which displays binding affinities across MC1R, MC3R, MC4R, and MC5R), Melanotan I acts as a highly potent, selective agonist of the Melanocortin 1 Receptor (MC1R). This targeted selectivity minimizes systemic off-target physiological interactions while driving melanogenesis within epidermal melanocytes, making it an essential reference compound for photodermatology and skin photoprotection studies.
B2B enterprise buyers, pharmaceutical contract research organizations (CROs), and bulk distributor networks require consistent, high-purity (≥99.0%) 10mg lyophilized vials of Melanotan I due to several primary global drivers:
OEM manufacturing parameters for Melanotan I 10mg engineered via advanced Solid-Phase Peptide Synthesis (SPPS) and preparative HPLC.

|---|---|---|---|
| Chemical Purity | ≥ 98.0% | ≥ 99.0% (Batch Average 99.4%) | RP-HPLC (Reverse Phase HPLC) |
| Molecular Mass Verification | 1646.85 Da ± 1 Da | 1646.85 Da (Conforms) | LC-MS (ESI-MS Electro-spray Ionization) |
| Lyophilized Appearance | Off-white / Cake Powder | Pure White Lyophilized Uniform Cake | Visual Inspection in Cleanroom Class 100 |
| Bacterial Endotoxins | < 10 EU/mg | < 0.05 EU/mg (Ultra-Sterile) | LAL Kinetic Chromogenic Method |
| Residual Moisture Content | < 5.0% | < 1.5% | Karl Fischer Titration |
| Counterion Content (TFA) | Variable (< 10%) | < 1.0% / Acetate Exchange Available | Ion Chromatography (IC) |
| Heavy Metals Total | < 20 ppm | < 5 ppm | ICP-MS Validation |
Melanotan I is assembled on a high-throughput solid support resin (such as Rink Amide Resin) utilizing orthogonal Fmoc protection strategies. Coupling reagents like HATU/DIPEA ensure near-100% coupling efficiency per amino acid addition, minimizing deletion sequences.
Global raw synthesis crude undergoes cleavage using optimized cocktail solutions (TFA/EDT/TIS/H2O). Crucially, Gentolex executes specialized ion-exchange chromatography to convert TFA salts into biocompatible acetate counterions when requested by OEM clients.
Purification is performed using C18 reverse-phase preparative columns. Fractions showing purity ≥99.0% are pooled, ultra-filtered, filled in 10mg ISO-certified vials, and subjected to a 48-hour automated vacuum lyophilization cycle.

To eliminate time-zone frictions and provide immediate technical consultation, Gentolex maintains established direct regional representations in key commercial territories including Mexico and South Africa, serving over 10 global regional markets.
Melanotan I 10mg lyophilized vials are packaged in temperature-controlled insulating containers with calibrated blue-ice/dry-ice systems. Real-time temperature logging ensures peptide chain stability (2–8°C) throughout international transport transit.
Every OEM batch is accompanied by comprehensive quality control documentation, including Analytical Batch Certificates (CoA), RP-HPLC Spectra, Mass Spectrometry (MS) verification graphs, and Material Safety Data Sheets (MSDS).
Expert technical insights regarding Melanotan I 10mg procurement, custom packaging, purity standards, and regulatory clearance.
All OEM batches of Melanotan I 10mg undergo double-stage High-Performance Liquid Chromatography (RP-HPLC) purification, guaranteeing a chemical purity profile of ≥99.0%. Detailed analytical CoA and MS reports are included with each lot.
Yes. We specialize in comprehensive OEM/ODM solutions. Clients can specify custom vial sizes (2ml, 3ml, 10ml ISO vials), custom flip-off cap colors/engravings, customized box packaging, and target fill weights (e.g., 5mg, 10mg, or bulk lyophilized cake format).
Melanotan I (Afamelanotide) is a linear peptide derived from α-MSH that selectively binds to the MC1R receptor. Melanotan II is a cyclic heptapeptide that non-selectively targets MC1R, MC3R, MC4R, and MC5R. Melanotan I offers higher target selectivity for photoprotection research without off-target CNS/MC4R activation.
Standard SPPS synthesis leaves residual TFA counterions. Upon client request, Gentolex performs an ion-exchange process to replace TFA with biocompatible Acetate salts, reducing TFA levels below 1.0% for sensitive biological assays.
Lyophilized Melanotan I 10mg vials remain stable at 2°C to 8°C for 24 months. For extended long-term storage, storing at -20°C to -80°C is recommended. Avoid exposure to light, moisture, and repeated freeze-thaw cycles after reconstitution.
Production occurs within cleanroom environments adhering to cGMP protocols. Endotoxin levels are measured via Kinetic Chromogenic Limulus Amebocyte Lysate (LAL) testing, verifying endotoxin control under <0.05 EU/mg.
