Methods of Manufacturing

The preparation method is similar to that of 1, 1-dimethylguanidine sulfate. Disperse S-methylisothiourea in cold water, add ethylamine aqueous solution and stir to react. After the reaction, concentrate under reduced pressure, cool, crystallize, and filter. , Washed with ethanol and dried to obtain the finished product. In addition, cyanamide solution can also be used to react with ethylamine to generate 1-ethylguanidine sulfate.

Uses

1-Ethylguanidine sulfate is an intermediate of the fungicide pyrimethoxine.
