Synthetic tetrapeptide
For laboratory research use only. Not for human consumption.
A synthetic tetrapeptide, referred to in the literature as SS-31. Sequence, CAS, and molecular formula: [VERIFY].
Supplied for laboratory research use. No third-party certificate of analysis has been published for this compound yet, so no purity figure is claimed for it. A published HPLC certificate will accompany it once a batch is tested.
Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's protocols. Not for human consumption.
Chemical identifiers marked [VERIFY] are pending verification and must not be treated as confirmed.
Also known asElamipretide · MTP-131 · Bendavia · Szeto-Schiller peptide 31
SS-31 is a synthetic tetrapeptide — D-Arg-Dmt-Lys-Phe-NH2, in which Dmt is 2,6-dimethyltyrosine — supplied as a lyophilized powder for laboratory research use only. It appears in the literature under the name elamipretide and under the development codes MTP-131 and Bendavia.
Its alternating aromatic and cationic residues give it a charge-and-hydrophobicity profile that the mechanistic literature describes as concentrating the peptide at the inner mitochondrial membrane without depending on membrane potential, which is the structural feature most of that work is concerned with.
The reported interactions center on cardiolipin, a phospholipid largely confined to the inner mitochondrial membrane. Biophysical work characterizes binding to lipid bilayers and modulation of membrane surface electrostatics; chemical-crosslinking mass spectrometry has been used to map which mitochondrial proteins sit within range of the bound peptide.
Structure-activity work across related tetrapeptide analogues examines which residues account for the observed membrane association. The literature listed below is in-vitro, cell-free, and preclinical: it reports binding measurements and bioenergetic readouts in isolated systems.
Reported mechanism · literatureIn the mechanistic literature SS-31 is characterized as a mitochondria-targeting tetrapeptide that associates with cardiolipin in the inner mitochondrial membrane and alters the local lipid environment and surface charge, with reported consequences for the organization of electron-transport components as measured in isolated mitochondria and in cell-free bilayer systems.

Species in the cited literaturePublished research involving SS-31 includes work carried out in dogs. This records which animals the cited work used — the same kind of fact as a journal or a year. It is not a statement about outcomes, and nothing here is veterinary guidance.
Format is illustrative. We present no assay %, residual-solvent, or lot figures until a real batch is tested and its certificate published. For laboratory research use only. See our full standard →
SS-31 is a synthetic tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2, where Dmt is the non-standard residue 2,6-dimethyltyrosine. It is also known as elamipretide, MTP-131, and Bendavia. Ouralus supplies it as a lyophilized powder for laboratory research use only.
C32H49N9O5 (molar mass ≈ 639.8 g/mol; PubChem CID 11764719, CAS 736992-21-5, UNII 87GWG91S09). The alternating aromatic and basic residues, and the C-terminal amide, are what distinguish it from a conventional linear tetrapeptide.
These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.
SS-31 is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.
Ouralus third-party HPLC-tests its catalogue lots and publishes the certificate of analysis per product as each report is finalized. A certificate is not posted for SS-31 yet, so treat its identity and purity as unconfirmed until one appears here. Supplied as a research chemical for laboratory use only.
