SNAP-8, also known as Acetyl Octapeptide-3, is an eight-residue acetylated peptide supplied for controlled laboratory, analytical, and scientific research.

Its defined structure includes an N-terminal acetyl modification, a linear eight-residue peptide backbone, and C-terminal amidation. PubChem lists Acetyl Octapeptide-3 with CAS 868844-74-0, molecular formula C₄₂H₇₂N₁₆O₁₅S, and molecular weight approximately 1073.2 g/mol.

Because terminal modifications form part of its chemical identity, SNAP-8 should be documented using the complete modified sequence rather than the amino-acid letters alone.

Research Applications

SNAP-8 may be examined in controlled non-clinical research involving:

  • Peptide identity and characterization
  • Modified peptide analysis
  • Molecular interaction studies
  • Structure-function research
  • Comparative peptide studies
  • Stability assessment
  • Chromatographic characterization
  • Non-clinical biochemical models

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

Structural Information

SNAP-8 is represented as:

Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH₂

Abbreviated sequence:

EEMQRRAD

Important structural features include:

  • N-terminal acetylation
  • Eight amino-acid residues
  • C-terminal amidation

These modifications should be preserved in technical documentation.

Salt-Form Considerations

SNAP-8 may also be supplied in acetate-associated form.

PubChem lists SNAP8 Acetate with:

  • Molecular Formula: C₄₃H₇₄N₁₆O₁₈S
  • Molecular Weight: Approximately 1135.2 g/mol
  • Condensed Structure: Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH₂ · CH₃CO₂H

Therefore, free-base and acetate specifications should not be used interchangeably.

Analytical Identification

Relevant analytical characterization may include:

  • Peptide sequence confirmation
  • Molecular mass assessment
  • Terminal-modification verification
  • Counter-ion identification
  • Chromatographic purity analysis
  • Structural characterization
  • Lot-specific quality testing

Specifications & Documentation

Lot-specific documentation should be reviewed for:

  • Product identity
  • Amino-acid sequence
  • Terminal modifications
  • CAS number
  • Molecular formula
  • Molecular weight
  • 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 conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that may compromise peptide integrity.

Handling should follow established laboratory procedures appropriate for research materials.
