1,2,3-Thiadiazol-5-amine - Reference Information
| use | 5-amino -1,2, 3-thiadiazole is an intermediate of defoliant setaxolone. Used as pesticide intermediate pharmaceutical intermediate. |
| Production method | The preparation method is based on the diazotization reaction of aminoacetonitrile, acetic acid and sodium nitrite to obtain diazo acetonitrile, and hydrogen sulfide is introduced into diazo acetonitrile and triethylamine. The product is obtained by methylene chloride solution. Diazo acetonitrile solution is very unstable and prone to explosion, so special attention should be paid. It can also be used to react chloroacetaldehyde and ethyl hydrazine formate to obtain ClCH2CN = NNHCOOC2H5, and then further react with thionyl chloride to obtain 5-chloro-1, 2, 3-thiadiazole, and then in dimethylformamide The solvent reacts 5-chloro-1, 2, 3-thiadiazole with ammonia to obtain the product. |
