Research context
Epithalon is a synthetic tetrapeptide, Ala-Glu-Asp-Gly, with the molecular formula C14H22N4O9 and a molecular weight of 390.35 g/mol. It is studied in cellular and telomere research as a characterized reference material, and its identity is confirmed by mass spectrometry against the expected molecular formula.
Supplied solely as a characterized research material. No representation is made as to any biological effect. For Research Use Only — not for human or veterinary use.
How Epithalon is identified
Identity and purity are measured, not asserted. Electrospray mass spectrometry (ESI-MS) determines the mass-to-charge ratio of the intact molecule — an observed value matching the expected series above confirms the molecular formula. Reversed-phase HPLC separates the sample over time, and purity is read as arithmetic: the target peak’s area as a share of total peak area.
