Methoxyethylamine monosubstituted β-cyclodextrin, mono-6(A)-(2-methoxyethyl-1-ammonium)-6(A)-β-cyclodextrin chloride (MEtAMCD), is synthesized and analytically characterized. Bearing a methoxy group in cyclodextrin rim, MEtAMCD exhibits outstanding enantioselectivities toward ampholytic and acidic racemates in capillary electrophoresis. Driven by inclusion complexation, electrostatic interactions and/or hydrogen bonding, the
