The fragmentation of methyl O-methyl-D-xylofuranosides under conditions of electron-impact mass spectrometry has been studied and compared with that of fully methylated methyl pentofuranosides. Characteristic differences in fragmentation of the differently substituted methyl O-methyl-D-xylofuranosides have been found which permit unambiguous assignment of both the number and the location of the methyl groups. Thus, compounds in this series can be identified without derivatization prior to the analysis. The g.l.c.-m.s. technique can be conveniently used to identify the products of methanolysis of methylated polysaccharides.
