Description

Melanotan II is a synthetic cyclic peptide supplied for controlled laboratory and analytical research. Its molecular structure incorporates modified amino-acid residues, including norleucine and D-phenylalanine, together with an intramolecular cyclization between the aspartic acid and lysine residues.

These structural characteristics distinguish Melanotan II from conventional linear peptides and make it suitable for scientific work involving peptide characterization, receptor-associated biochemical systems, molecular interactions, structural analysis, and related non-clinical experimental models.

Confirm the exact material form, purity specification, counter-ion status, and analytical profile using the applicable Certificate of Analysis.

Research Applications

Melanotan II may be examined in controlled scientific environments involving:

• Cyclic peptide characterization
• Molecular interaction studies
• Receptor-associated biochemical research
• Structure-activity investigations
• Analytical peptide comparison
• Stability and structural studies
• Non-clinical cellular or molecular models

Any observations should remain specific to the experimental system in which they were generated and should not be interpreted as demonstrating cosmetic, therapeutic, or clinical effectiveness.

Structural Information

Melanotan II is a cyclic peptide commonly represented as:

Ac-Nle-Asp(1)-His-D-Phe-Arg-Trp-Lys(1)-NH₂

The notation (1) identifies the residues participating in the peptide’s cyclized structure. The N-terminus is acetylated and the C-terminus is amidated.

Analytical Identification

Analytical characterization may include:

• Peptide identity confirmation
• Molecular mass analysis
• Chromatographic purity testing
• Structural verification
• Cyclic peptide confirmation
• Lot-specific quality analysis

If supplied as an acetate or another salt form, the molecular formula and molecular weight may differ from the free-peptide reference values.

Specifications & Documentation

Lot-specific documentation should be reviewed for:

• Compound identity
• Structural representation
• Molecular formula
• Molecular weight
• Purity specification
• Salt or counter-ion form
• Analytical testing
• Lot or batch identification
• Certificate of Analysis
• Storage requirements

Authenticated lot-specific data should take precedence over generalized chemical reference information.

Storage & Handling

Store according to the conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that could compromise peptide integrity.

Handle using established laboratory procedures appropriate for research materials.
