The mass spectra of the O‐isopropylidene derivatives of threo ‐ and erythro ‐furanose and those of the four C(4) methylated stereoisomers have been studied. Fragmentation modes based upon deuterium labelling, metastable peaks and high‐resolution measurements are proposed. Each stereoisomer can be characterized by its low‐resolution mass spectrum.
