1,2,3,4-Tetrahydro-2,4-dioxo-6-pyrimidine-carboxylicacidmonohydrate - Reference Information
| biological activity | 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid hydrate is an endogenous metabolite. |
| use | akamin intermediate. It can also be used as animal feed additive and growth promoter. |
| Production method | Diethyl oxalate and ethyl acetate are condensed by Claisen, and then cyclized with urea under acid catalysis to generate 5-ethoxycarbonylmethylene caprolacyl urea, which is then rearranged under the action of sodium hydroxide to obtain orotate, acidification to obtain this product, which can also be prepared by microbial fermentation. |
