MT-1, also known as Melanotan I or Afamelanotide, is a synthetic 13-residue peptide supplied for controlled laboratory, analytical, and scientific research.

Its structure includes an N-terminal acetyl group, a norleucine residue, D-phenylalanine, and C-terminal amidation. These features distinguish MT-1 from the corresponding unmodified peptide sequence and form part of its complete molecular identity.

PubChem lists Afamelanotide/Melanotan I with CAS 75921-69-6, molecular formula C₇₈H₁₁₁N₂₁O₁₉, molecular weight approximately 1646.8 g/mol, and the sequence shown above.

Research Applications

MT-1 may be examined in controlled non-clinical research involving:

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

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

Structural Information

MT-1 is represented as:

Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH₂

Important structural features include:

  • N-terminal acetylation
  • Norleucine substitution
  • D-phenylalanine residue
  • C-terminal amidation
  • Linear 13-residue peptide structure

MT-1 should not be confused with MT-2, which is a shorter cyclic peptide with a different molecular identity.

Analytical Identification

Relevant analytical characterization may include:

  • Amino-acid sequence confirmation
  • Modified-residue verification
  • Molecular mass assessment
  • Terminal modification confirmation
  • Chromatographic purity testing
  • Structural characterization
  • Lot-specific quality analysis

Specifications & Documentation

Lot-specific documentation should be reviewed for:

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

Authenticated product-specific documentation should take precedence over generalized 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.

Handling should follow established laboratory procedures appropriate for research materials.
