Structural & Stability Notes
5-Amino-1MQ is a low-molecular-weight quaternary ammonium compound featuring a positively charged quinolinium core. The permanent cationic charge enhances aqueous solubility and contributes to chemical stability under controlled laboratory conditions. The iodide counterion stabilizes the salt form, while the aromatic ring system provides structural rigidity. Due to its non-peptide nature, the compound is not subject to enzymatic peptide degradation and demonstrates favorable shelf stability when stored in a dry, light-protected environment.
