Chemical identity

What SNAP-8 is

SNAP-8 is the trade name of acetyl octapeptide-3 (INCI), also listed as acetyl glutamyl heptapeptide-3 or acetyl octapeptide-1. It is a synthetic linear octapeptide with an N-terminal acetyl group and a C-terminal primary amide: Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2 (Ac-EEMQRRAD-NH2). The single methionine residue accounts for the one sulfur atom in the formula. PubChem (CID 76283482, CAS 868844-74-0, UNII 8K14HJF88S) records the molecular formula C41H70N16O16S and a molecular weight of 1075.2 g/mol, which is the value calculated for the acetylated, amidated sequence; the Pepta Labs listing shows C42H72N16O15S and 1073.20 Da, and the mass observed for the sourced production run is stated on the analytical report. Pepta Labs supplies SNAP-8 as a lyophilized powder in a sealed glass vial (10 mg quantity), typically as an acetate or trifluoroacetate salt, with reported RP-HPLC purity and mass-spectrometric identity. Store at 2-8 C on arrival or at -20 C for long-term storage, protected from light and moisture. Laboratory research use only.

Questions

SNAP-8 10mg — common questions

What sizes of SNAP-8 does Pepta Labs sell?

One size: the 10 mg vial on this page. There is no larger single-vial SNAP-8 listing; if a project needs more material, order several 10 mg vials.

What exactly is in the SNAP-8 10mg vial?

A supplier-stated 10 mg of SNAP-8 (acetyl octapeptide-3) as dry lyophilized powder in a sealed glass vial. The 10 mg is the supplier-stated quantity, not a measured net peptide content; net peptide content, counter-ion share and residual water are not reported per listing, and the vial carries no lot number.

Is SNAP-8 supplied as the acetate or the TFA salt?

Synthetic acetyl octapeptide-3 is typically isolated as an acetate or trifluoroacetate (TFA) salt, and this listing does not state which counter-ion the sourced production run carries. Counter-ion content is not reported per listing; the analytical report covers RP-HPLC purity and mass-spectrometric identity for the sampled production run, and you can request it on this page or email support@peptalabs.com.

How do I get the SNAP-8 certificate of analysis (COA)?

Request it on this page or email support@peptalabs.com with the compound name SNAP-8 10mg; it is sent by email, before you order if you want it. The report covers the sampled production run, not a lot-specific certificate: purity is RP-HPLC area-percent and identity is by mass spectrometry. Sterility and endotoxin testing are not claimed. The Learn guide Peptide Registry Records: When PubChem, CAS and a Listing Disagree explains why a listing's formula can differ from a registry record.

How should the sealed SNAP-8 powder be stored?

Keep the sealed vial at 2-8 C on arrival, or at -20 C for long-term storage, away from light and moisture. It ships as dry powder at ambient temperature with no cold pack. The Learn guide on storage temperature and handling of lyophilized research peptides covers dry-powder storage in more detail.

What does SNAP-8 10mg cost?

SNAP-8 10mg starts at $36.99 per vial. 3-vial packs are 10% off and 5-vial packs are 15% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. SNAP-8 10mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

Is SNAP-8 the same as acetyl octapeptide-3?

Yes. SNAP-8 is the trade name; acetyl octapeptide-3 is the INCI name, and acetyl glutamyl heptapeptide-3 is an older INCI label for the same sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2 (CAS 868844-74-0, UNII 8K14HJF88S).

What do the Ac- prefix and -NH2 suffix in the sequence mean?

Ac- indicates that the N-terminal glutamate is acetylated (no free N-terminal amine) and -NH2 indicates that the C-terminal aspartate is a primary amide rather than a free acid. Together these modifications add about 41 Da relative to the unmodified octapeptide and are included in the PubChem formula C41H70N16O16S (1075.2 g/mol).

Which molecular weight should be expected on the analytical report?

The calculated average molecular weight of Ac-EEMQRRAD-NH2 is 1075.2 g/mol (PubChem CID 76283482); the site listing shows 1073.20 Da. The mass spectrum on the analytical report gives the observed mass for the sourced production run.
