D-Galactal Chemical Properties, Uses, Production

Chemical Properties

White Powder

Uses

D-Galactal is an important building block for both solution- and solid-phase synthesis of oligosaccharides.

Definition

ChEBI: D-galactal is a glycal derived from D-galactopyranose It is a glycal and an anhydrohexose.

Synthesis

The preparation of D-galactal in the presence of D-galactose,glycol, water and β-galactosidase.

Purification Methods

Recrystallise D-galactal from EtOAc, EtOH or EtOAc/MeOH. [Overend et al. J Chem Soc 675 1950, Wood & Fletcher J Am Chem Soc 79 3234 1957, Distler & Jourdian J Biol Chem 248 6772 1973, Beilstein 17 III/IV 2332.]
