High-resolution electrospray mass spectra (MS and MS/MS CID) of pos. ions of a series of protonated, ammoniated, and metalated mols. of cyclic N-substituted oligo-β-(1→6)- D-glucosamines differing in cycle size and N-acyl substituents were registered and interpreted. It was shown that the main type of fragmentation is a cleavage of glycosidic bonds of a cycle, and in some cases fragmentation of amide side chains is possible. If labile fragments in substituents (e.g., carbohydrate chains) are present, a decay of the cycle and an elimination of labile fragments are of comparable possibility. It was found that in some cases rearrangements with loss of an internal carbohydrate residue (IRL), or an internal part of a side chain, are feasible. In the part of experimental materials, we found many familiar compounds, such as rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Related Products of 54-17-1)
