D-Galactal Usage And Synthesis
Chemical PropertiesWhite Powder
UsesD-Galactal is an important building block for both solution- and solid-phase synthesis of oligosaccharides.
DefinitionChEBI: D-galactal is a glycal derived from D-galactopyranose It is a glycal and an anhydrohexose.
Purification MethodsRecrystallise 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.]
