The product is obtained through the enzymatic transformation of the substrate-uridine monophosphate, then the chromatographic fractionation and purification in the ion-exchange column, the content of which is no less than 80%.

The product is a white powder, freely soluble in water, practically insoluble in ethanol. In condition of pH2, the ratio of A₂₅₀/A₂₆₀ =0.73±0.05, the ratio of A₂₈₀/A₂₆₀ =0.39±0.03, and its λmax is in 262±1nm.

Uridine diphosphate disodium salt can be used as the intermedium in pharmaceutical and chemical industry, and also as a biochemical reagent.
