Core Molecular Specs & Technical Index
MT2, or Melanotan II, is a synthetic peptide analog of the naturally occurring hormone alpha-melanocyte-stimulating hormone (α-MSH). For B2B buyers in cosmetic formulation and laboratory research, understanding the precise molecular specifications is the first step in evaluating raw material quality. The core value of MT2 lies in its ability to stimulate melanogenesis through the melanocortin 1 receptor (MC1R), making it a high-demand ingredient for advanced cosmetic products and research applications.
Basic Properties and Purity Standards
The molecular formula of MT2 is C50H69N15O9, with a molecular weight of 1024.2 g/mol. It is supplied as a lyophilized white powder, typically in acetate salt form. The minimum purity threshold for commercial-grade MT2 is 98%, while premium research-grade material often exceeds 99% as verified by HPLC analysis. Impurities such as truncated sequences, oxidation byproducts, or residual solvents must be strictly controlled below 0.5% each.
- Purity (HPLC): ≥98% for standard cosmetic grade; ≥99% for laboratory research grade
- Solubility: Freely soluble in water and saline solutions; recommended reconstitution at 1-2 mg/mL
- Storage Conditions: Lyophilized powder stable at -20°C for 24 months; reconstituted solution stable at 2-8°C for 7 days
- Appearance: White to off-white lyophilized powder, free of visible particulates
- pH Range: 4.5-6.5 in aqueous solution at 1 mg/mL concentration
Industry data from the Peptide Research Association (2023) indicates that 94% of commercial peptide failures are linked to purity below 97% or improper storage conditions. Buyers sourcing MT2 should always request a Certificate of Analysis (CoA) with HPLC chromatogram and mass spectrometry verification.
Manufacturing & Quality Control
The production of high-grade MT2 follows a rigorous multi-step process that directly impacts the final product's performance and safety profile. B2B buyers must understand these manufacturing standards to evaluate supplier reliability.
Production Process
MT2 is synthesized using solid-phase peptide synthesis (SPPS) with Fmoc chemistry. The process involves sequential coupling of protected amino acids on a resin support, followed by cleavage and deprotection. Each batch undergoes a minimum of three purification cycles using preparative HPLC to achieve the target purity level. The final product is lyophilized under controlled conditions to maintain structural integrity.
Quality Control Protocols
Reputable manufacturers implement a comprehensive QC framework that includes:
- HPLC Analysis: Quantifies purity and detects related impurities down to 0.1%
- Mass Spectrometry (MS): Confirms molecular weight and sequence identity
- Amino Acid Analysis: Verifies correct composition and peptide content
- Residual Solvent Testing: Ensures levels below ICH Q3C limits
- Endotoxin Testing: Must be below 1.0 EU/mg for research-grade material
- Moisture Content: Typically below 5% for lyophilized powder
Third-Party Certification Requirements
For B2B transactions, the following certifications are essential: ISO 9001 for quality management, GMP compliance for manufacturing facilities, and independent third-party lab reports for each batch. Suppliers providing full traceability documentation from raw material sourcing to final packaging demonstrate higher reliability.
Commercial Application Scenarios
Understanding mt2 what does it do in practical commercial contexts helps buyers select the right grade and quantity for their specific needs.
Cosmetic Formulation
In the cosmetic industry, MT2 is incorporated into topical formulations designed to promote even skin pigmentation. Formulators typically use concentrations of 0.001% to 0.01% in creams, serums, or lotions. The peptide's stability in formulation depends on pH (optimal 5.0-6.5) and the presence of antioxidants to prevent oxidation. Cosmetic-grade MT2 must be free of endotoxins and meet cosmetic ingredient safety standards.
Laboratory Research
Research laboratories use MT2 for studying melanocortin receptor signaling, pigmentation pathways, and potential applications in dermatological research. Typical research quantities range from 10 mg to 100 mg per study. Research-grade MT2 requires purity ≥99% and full characterization data to ensure reproducible results.
Bulk Wholesale Usage
Bulk buyers, including peptide distributors and large-scale formulators, typically order MT2 in quantities of 1 gram to 100 grams. Bulk pricing advantages become significant at 5-gram and above orders, with discounts ranging from 15% to 40% compared to small quantities. Bulk material should be packaged in airtight, light-resistant containers with desiccant to maintain stability during storage and transit.
mt2 what does it do VS Ordinary Low-Grade Peptides
| Item | Our Product (Premium MT2) | Alternatives (Low-Grade Peptides) | Advantages |
|---|---|---|---|
| Purity (HPLC) | ≥99% | 90-95% | Higher purity reduces side reactions and improves formulation consistency |
| Impurity Profile | Single impurity ≤0.3% | Multiple impurities up to 5% | Lower risk of unwanted biological activity or toxicity |
| Endotoxin Level | <0.5 EU/mg | >5 EU/mg | Safe for research and cosmetic applications |
| Batch Consistency | CV <2% across batches | CV >10% across batches | Reliable performance in formulation and research |
The comparison clearly demonstrates that premium MT2 offers superior quality metrics that directly translate to better performance in commercial applications. Low-grade peptides often contain truncated sequences that can interfere with receptor binding and produce inconsistent results.
Bulk Purchase Selection Guide
B2B buyers face several common pitfalls when sourcing MT2 in bulk quantities. Understanding these challenges and implementing proper selection criteria ensures a successful procurement process.
Common Pitfalls
- Incomplete Documentation: Suppliers unable to provide full CoA with HPLC and MS data
- Misleading Purity Claims: Some suppliers report "purity" based on UV absorption without proper impurity quantification
- Inadequate Packaging: Bulk material shipped without desiccant or in non-airtight containers leads to moisture absorption and degradation
- Unverified Storage History: Material that has experienced temperature excursions during shipping may have reduced potency
Selection Standards
When evaluating MT2 suppliers, request the following: HPLC chromatogram with peak integration, mass spectrometry confirmation, amino acid analysis report, and residual solvent analysis. Always verify that the supplier's facility is GMP-compliant and that third-party testing is conducted by an ISO 17025 accredited laboratory.
Buyer Checklist
- Request sample for in-house testing before bulk order
- Verify purity ≥98% for cosmetic grade, ≥99% for research grade
- Confirm endotoxin levels below 1.0 EU/mg
- Check packaging integrity and storage conditions
- Review supplier's quality management certifications
- Establish clear return and replacement policies
Core Product Advantages
Premium MT2 offers distinct advantages that justify its selection over lower-grade alternatives. Purity above 99% ensures minimal interference from impurities in both research and formulation contexts. The high stability profile, with proper storage maintaining potency for over 24 months, reduces waste and inventory management costs. Cost performance is optimized through bulk pricing structures that reward larger orders without compromising quality. Additionally, suppliers offering technical support for formulation development and application guidance provide added value for B2B clients.
Frequently Asked Questions
Q1: What is the difference between cosmetic-grade and research-grade MT2?
Cosmetic-grade MT2 typically has purity ≥98% and must meet cosmetic ingredient safety standards including low endotoxin levels and absence of heavy metals. Research-grade MT2 requires purity ≥99% with full characterization data including HPLC, MS, and amino acid analysis. Research-grade material is suitable for laboratory studies where precise molecular identity is critical.
Q2: How should MT2 be stored to maintain maximum stability?
Lyophilized MT2 powder should be stored at -20°C in airtight, light-resistant containers with desiccant. Under these conditions, stability is maintained for up to 24 months. Reconstituted solutions should be used within 7 days when stored at 2-8°C. Avoid repeated freeze-thaw cycles as this can degrade the peptide structure.
Q3: What documentation should I request when purchasing MT2 in bulk?
Request a Certificate of Analysis (CoA) that includes HPLC chromatogram with purity percentage, mass spectrometry confirmation of molecular weight, amino acid analysis, residual solvent testing, endotoxin levels, and moisture content. Also request GMP certification for the manufacturing facility and third-party lab accreditation documents.
