Fragmentation of the acetates of the N‐phenylosotriazoles of some mono‐, di, tri‐, tetra‐ and pentasaccharides under electron‐impact (EI) has been studied. The mass spectra of these derivatives can be used for determination of the sequence of monosaccharide units in oligosaccharides (oligosaccharide sequencing), of molecular weight, of the location of the position of the interglycosidic bond in disaccharides and of the position of the methyl group in partially methylated monosaccharides.
