MT-2, also known as Melanotan II, is a synthetic cyclic seven-residue peptide supplied for controlled laboratory, analytical, and scientific research.

Its molecular structure includes N-terminal acetylation, norleucine, D-phenylalanine, C-terminal amidation, and an intramolecular cyclic linkage. These structural features distinguish MT-2 from linear MT-1.

PubChem lists Melanotan II with CAS 121062-08-6, molecular formula C₅₀H₆₉N₁₅O₉, molecular weight approximately 1024.2 g/mol, and condensed sequence Ac-Nle-Asp(1)-His-D-Phe-Arg-Trp-Lys(1)-NH₂.

Research Applications

MT-2 may be examined in controlled non-clinical research involving:

  • Cyclic peptide characterization
  • Ligand-receptor interaction studies
  • Molecular signaling research
  • Structure-function analysis
  • Analytical peptide comparison
  • Conformational studies
  • Stability assessment
  • Non-clinical biochemical and cellular models

Experimental observations should remain limited to the applicable research system and should not be interpreted as evidence of cosmetic, pigmentation-related, behavioral, therapeutic, or clinical effectiveness.

Structural Information

MT-2 is represented as:

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

Key structural features include:

  • N-terminal acetylation
  • Norleucine residue
  • D-phenylalanine
  • Cyclic peptide linkage
  • C-terminal amidation

MT-2 is therefore chemically and structurally distinct from MT-1.

Analytical Identification

Relevant characterization may include:

  • Peptide identity confirmation
  • Sequence verification
  • Cyclic linkage confirmation
  • Modified-residue verification
  • Molecular mass assessment
  • Chromatographic purity testing
  • Structural analysis
  • Lot-specific quality testing

Specifications & Documentation

Lot-specific documentation should be reviewed for:

  • Compound identity
  • Peptide sequence
  • Molecular formula
  • Molecular weight
  • Cyclization state
  • Salt or counter-ion form
  • Purity specification
  • Analytical testing
  • Lot or batch information
  • Certificate of Analysis
  • Storage requirements

Authenticated lot-specific documentation should take precedence over generalized reference values.

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.

Handling should follow established laboratory procedures appropriate for research materials.
