The potential applications of N-hexyl-4-aminobutyl glycosides in the mass spectrometric investigation of glycan structure and in the investigation of glycan functions were studied. Under collision-induced dissociation (CID) conditions, sodiated glycosides carrying N-hexyl- 4-aminobutyl groups effectively produced a hemiacetal species (C-ions), which is important in mass-spectrometry-based structural investigation. The usefulness of N-hexyl-4- ...
