Research context
5-Amino-1MQ is a small-molecule quinolinium derivative, 5-amino-1-methylquinolinium, supplied as the iodide salt, with the molecular formula C10H11IN2 and a molecular weight of 286.12 g/mol. It is a characterized chemical reference material — not a peptide — and its identity is confirmed by 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 5-Amino-1MQ 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.
