Abstract
A process for the preparation of crystalline monosodium guanosine-5'-diphosphate dihydrate, comprising: a) preparing an aqueous solution of guanosine-5'-diphosphoric acid or a sodium salt thereof, the aqueous solution of which is obtained as such or is it produces by dissolving a sodium salt of guanosine-5'-diphosphoric acid in water which may optionally contain a hydrophilic solvent; b) adjust the ph value of the solution to the range of 1.0 to 3.0 by adding it to an acidic material or an alkaline sodium material or adding nothing to obtain an aqueous solution of guanosine-5-diphosphate monosodium at ph 1.0º3.0; and c) reducing the solubility of the monosodium guanosine-5-diphosphate contained in said solution to precipitate the guanosine-5-diphosphate monosodium dihydrate, carrying out this step at a temperature not higher than 30º c.
