| | 2,6-Difluorobenzonitrile Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powder | | Uses | 2,6-Difluorobenzonitrile is a halogenated benzonitrile with fungacidal activity. 2,6-Difluorobenzonitrile is the difluoro analogue of the herbicide Dichlobenil. | | Uses | 2,6-Difluorobenzonitrile was used in the synthesis of:
- poly(cyanoaryl ethers) via silyl-method
- 2-dimethylamino-6-fluorobenzamide
- phenolphthalein-modified polyarylene ether nitrile copolymers
| | Flammability and Explosibility | Non flammable | | Synthesis | 2,6-Difluorobenzonitrile [1897-52-5], 1- cyano-2,6-difluorobenzene, Mr 172.02, mp 29 – 30℃, forms colorless crystals. The nitrile can be produced by treatment of 2,6-dichlorobenzonitrile with potassium fluoride in sulfolane and is used as an intermediate in the synthesis of insecticides (e.g., Dimilin, Shell). | | Toxics Screening Level | The initial threshold screening level (ITSL) for 2,6-difluorobenzonitrile (DFBN) is 0.2 μg/m3 based on an annual averaging time. |
