Products Description of D-(-)-ERYTHROSE CAS#583-50-6
D-(-)-Erythrose, is a four-carbon aldose monosaccharide with molecular formula C4H8O4. It is normally supplied as a colorless to pale yellow viscous syrup. It is highly soluble in water and soluble in methanol and ethanol, with characteristic aldose reactivity. It exists as a chiral carbohydrate and is an isomer of D-threose.
This product is prone to oxidation and polymerization, so it needs sealed, light-shielded storage under cool and dry conditions to maintain its purity and stability. It is widely used as a carbohydrate building block for biochemical research and custom organic synthesis.
