[Chemical Properties]

white crystalline compound
[Uses]

Isotope labelled analogue of D-Arabinose (A764175), an inhibitor of the enzyme glucose dehydrogenase.
[Uses]

pharmaceutical intermediate; food additive
[Definition]

ChEBI: Aldehydo-D-arabinose is an aldehydo-arabinose and a D-arabinose. It is an enantiomer of an aldehydo-L-arabinose.
[Purification Methods]

Crystallise D-(-)-arabinose three times from EtOH, dry it in vacuo at 60o for 24hours and store it in a vacuum desiccator. It also crystallises from a mixture of H2O/MeOH/EtOH with m 158-160o, or H2O with m 160-161o. [Whistler & Schweiger J Am Chem Soc 81 5190 1959, Fletcher et al.
