Research context
MT-1 (Melanotan 1) is a synthetic 13-residue α-MSH analog with the molecular formula C78H111N21O19 and a molecular weight of 1646.87 g/mol. It is studied in melanocortin-signaling research as a characterized reference material and is verified by reversed-phase HPLC and mass spectrometry.
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 MT-1 (Melanotan 1) 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.
