Research context
MT-2 (Melanotan 2) is a synthetic cyclic α-MSH analog of seven residues, with the molecular formula C50H69N15O9 and a molecular weight of 1024.20 g/mol. It is studied in melanocortin-signaling research and is supplied as a characterized reference material, with identity 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 MT-2 (Melanotan 2) 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.
