4,6-Dihydroxy-2-methylthio pyrimidine - Reference Information
| Use | 4, 6-dihydroxy-2-methylthiopyrimidine is the herbicide fluorimuron imuron and pyrimidine salicylic acid herbicides diimuron (bispyribac),pyriminobac and imuron sulfide (pyrithiobac) intermediate. |
| production method | the preparation method is to add diethyl malonate, thiourea and solvent to the reaction bottle, heat to reflux, add acid binding agent dropwise, react for several hours, cool, and filter to obtain 4, 6-dihydroxy-2-mercaptopyrimidine. Then, the thiopyrimidine is dissolved in the acid binding agent, dimethyl sulfate is added, and after stirring for several hours, the reaction liquid is heated to boiling, and then activated carbon is added to decolorization and filter, and the filtrate is cooled and acidified with sulfuric acid to generate white crystals as finished products. Using diethyl malonate to react with S-methyl isothiourea salt, 2-methylthio -4, 6-dihydroxypyrimidine can also be obtained. |
