How to Read a SS-31 Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For SS-31, the informative checks are not the same as for a generic short peptide.
Overview
Check the weight near 640 and that the shape (stereochemistry) and its special methylated building block are intact.
What SS-31 actually is
A tiny four-part peptide that homes in on the powerhouse of the cell, sticking to a lipid (cardiolipin) found only in the inner mitochondrial membrane. Studied around cellular energy, oxidative stress, and aging. Also called Elamipretide.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for SS-31
What to check on the COA
Confirm the mass near 639.8 Da and check stereochemistry — the D-residue and the dimethyltyrosine are essential, so diastereomer or des-methyl impurities are the characteristic things to look for.
Diastereomers from partial racemisation and des-methyl tyrosine related substances.

What SS-31 is studied for
Studied for selective association with cardiolipin in the inner mitochondrial membrane, the basis of its mitochondrial targeting.
Examined for effects on mitochondrial energy production in research models of mitochondrial dysfunction.
Investigated around reactive-oxygen-species handling at the mitochondrion.
