Research context
Ipamorelin is a synthetic pentapeptide, Aib-His-D-2-Nal-D-Phe-Lys, with the molecular formula C38H49N9O5 and a molecular weight of 711.87 g/mol. It is studied in secretagogue and receptor research and is supplied as a characterized reference material, verified by mass spectrometry and reversed-phase HPLC.
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 Ipamorelin 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.
