Chemical identity

What MOTS-C is

MOTS-c is a synthetic linear 16-residue peptide with the sequence Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Arg (one-letter MRWQEMGYIFYPRKLR), free N-terminus and free C-terminal acid, matching the human-encoded sequence. It contains two methionine residues, which account for the two sulfur atoms in the molecular formula C101H152N28O22S2; the molecular weight is 2174.62 g/mol (monoisotopic mass 2173.13 Da). The CAS Registry Number is 1627580-64-6, PubChem CID 146675088 and UNII A5CV6JFB78. One tryptophan and two tyrosine residues give a strong UV absorbance at 280 nm that is useful for concentration measurement. Pepta Labs lists MOTS-c in 10 mg and 40 mg vials of lyophilized powder, typically as a trifluoroacetate or acetate salt, with reported RP-HPLC purity (99.1% on the current listing) and identity confirmed by mass spectrometry. Store sealed vials at 2-8 C short term or -20 C long term; methionine residues can oxidize, so keep dry and protected from air. For laboratory research use only.

Questions

MOTS-C 40mg — common questions

What is in a MOTS-c 40mg vial?

One sealed glass vial holding a supplier-stated 40 mg of MOTS-c as dry lyophilized powder, with no liquid added. Vial fill-quantity testing is not claimed and net peptide content is not reported per listing. The label names the compound, quantity and research-use designation and carries no lot number.

How is MOTS-C 40mg different from MOTS-C 10mg?

In the supplier-stated quantity per vial. Both listings are the same 16-residue peptide (MRWQEMGYIFYPRKLR) with CAS number 1627580-64-6, supplied as lyophilized powder in one sealed vial; the 40mg listing holds four times the supplier-stated quantity of the 10mg listing. Each size shows its own single-vial and pack prices on its own page.

Can I see the MOTS-c 40mg HPLC and mass spec report before ordering?

Yes. The report is sent by email on request, before or after you order: request it on this page or email support@peptalabs.com with the name MOTS-C 40mg. It comes from independent testing commissioned on a sampled production run and covers that run, not an individual vial; Pepta Labs does not test in-house. The Learn guide How to Read and Verify a Peptide Certificate of Analysis explains each field.

Is MOTS-C 40mg the same compound as MOTSc?

Yes. MOTSc, MOTS c and H-MRWQEMGYIFYPRKLR-OH are other names for the same 16-residue peptide, CAS 1627580-64-6. The MOTS-C 40mg and MOTS-C 10mg listings are both this compound, sold for laboratory research in different quantities per vial.

How should a 40 mg vial of MOTS-c powder be stored?

Unopened, keep it sealed and dry at 2-8 °C for short periods or at -20 °C for long-term storage, away from light. MOTS-c contains two methionine residues that can oxidize with air and moisture; let a cold vial reach room temperature before opening so condensation does not form on the powder.

What does MOTS-C 40mg cost?

MOTS-C 40mg starts at $102.87 per vial. 3-vial packs are 7% off and 5-vial packs are 14% 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. MOTS-C 40mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What is the sequence and length of MOTS-c?

MOTS-c is a 16-residue linear peptide, MRWQEMGYIFYPRKLR, with free N- and C-termini. Its formula is C101H152N28O22S2 and molecular weight 2174.62 g/mol; the two sulfur atoms come from its two methionine residues.

Why does a mass spectrum of MOTS-c sometimes show a +16 Da peak?

Each methionine can oxidize to methionine sulfoxide, adding 16 Da per oxidized residue (+16 or +32 Da total). Keeping the lyophilized powder dry, cold and protected from air limits this, and the analytical report shows the observed mass.

What does the CAS number 1627580-64-6 identify?

It is the CAS Registry Number for the human MOTS-c 16-residue sequence as the free peptide (PubChem CID 146675088, UNII A5CV6JFB78), independent of whether the material is supplied as a trifluoroacetate or acetate salt.
