D(+)-Xylose Chemical Properties,Usage,Production

  • Chemical Properties white crystals or powder
  • Chemical Properties D-Xylose is nearly odorless and has a smoky flavor.
  • Uses D-Xylose is used in diagnostic malabsorption tests as well as in the production of Furfural.
  • Uses sweetener, pharmaceutical intermediate
  • Uses An aldopentose monosaccharide.
  • Uses In tanning, dyeing, and as a diabetic food.
  • Definition A SUGAR that has five carbon atoms in its molecules.
  • Definition pentose: A sugar that has five carbonatoms per molecule.
  • Definition ChEBI: The pyranose form of D-xylose.
  • brand name Xylo-Pfan (Savage).
  • Purification Methods -D(+)-Xylose forms needles or prisms (which have a very sweet taste) by slow crystallisation from aqueous 80% EtOH or absolute EtOH, which are then dried at 60o in vacuo over P2O5. Store it in a vacuum desiccator over CaSO4. 1Gram dissolves in 0.8mL H2O.
