| titleOfInvention | Process for producing cmp-n-acetylneuraminic acid |
| abstract | A method by which high-purity CMP-N-acetylneuraminic acid (HPLC purity, 95% or higher), which has been difficult to obtain with any technique other than chromatography, can be easily obtained in satisfactory yield by a simple operation without the need of chromatography. The process, which is for producing high-purity CMP-N-acetylneuraminic acid (CMP-NeuAc), is characterized by conducting a suitable combination of the following steps (1) to (4). Step 1: a step in which divalent cations are added to a solution containing CMP-NeuAc to thereby precipitate the phosphoric acid, pyrophosphoric acid, and nucleotide which coexist; Step 2: a step in which a phosphatase is added to a solution containing CMP-NeuAc to thereby convert the coexistent nucleotide into nucleoside; Step 3: a step in which an organic solvent is added to precipitate the CMP-NeuAc; and Step 4: a step in which the CMP-NeuAc precipitated is recovered. |
