| Use | For pharmaceutical, is the drug triamterene Intermediate; For organic synthesis, gold leaching agent. |
| application | malononitrile is a nitrile organic substance, which can be used as an intermediate for pesticides and medicines. |
| Use | Malononitrile is a raw material for the preparation of 2-amino -4, 6-dimethoxypyrimidine and 2-chloro-4, 6-dimethoxypyrimidine. It can be used to produce sulfonylurea herbicides such as bensulfuron-methyl, pyrisulfuron-methyl, etc., and it can also be used to make herbicide bisoxyl, which is used to make diuretic drugs in medicine. Organic synthetic raw materials. In medicine, it is used to synthesize a series of important drugs such as vitamin B1, methotrexate, and triamterene. Dyes, pesticides and other aspects have important uses. It can also be used as an extractant for gold. China is now mainly used for the production of triamterene, bensulfuron, 1,4,5,8-naphthenic acid, pyrimidine series products. It is used in pharmaceuticals and is a drug triamterene intermediate It can be used as a raw material for organic synthesis, a pharmaceutical intermediate and an organic solvent. |
