Applications

1. Malononitrile is extensively used as a building block for the synthesis of vitamins, agrochemicals, pharmaceuticals and dyes

2. The two most important outlets for malononitrile are thiamine (vitamin B1) and the sulfonylurea herbicides based on 2-amino-4,6-dimethoxypyrimidine, such as benzsulfuron-methyl, azimsulfuron , pyrazosulfuron-ethyl [93697-74-6]and halosulfuron-methyl

3. Other outlets for malononitrile are the diuretic triamterene, the folic acid antagonist methotrexate both prepared from 2,4,6-triaminopyrimidine, adenine, the antihypertensive minoxidil, and the pesticide dicyclanil
