SS-31, developmentally known as Elamipretide, is a synthetic tetrapeptide that has drawn
significant interest in mitochondrial biology research circles. This article summarizes what the
compound is, how it is characterized analytically, and what “purity grade” means in a research
supply context — without making any claims about human therapeutic use.
Analytical Identity
Researchers typically confirm peptide identity via mass spectrometry (matching expected
molecular weight) and quantify purity via HPLC (high-performance liquid chromatography). These two
tests are the backbone of any credible Certificate of Analysis.
Why Purity Grading Matters
Not all “SS-31” listed online is tested to the same standard. A documented, batch-specific COA
is the only reliable way to know what purity and identity a given vial actually has.
