Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 218632-01-0, name is 3-Fluoro-4-nitrobenzonitrile, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of 3-Fluoro-4-nitrobenzonitrile
XIX.1 3-(2-Fluoro-1 -fluoromethyl-ethoxy)-4-nitro-benzonithle1 ,3-Difluoro-propan-2-ol (4.2 g) was dissolved under argon in THF (250 ml) and cooled to 0C. LiHMDS (28 ml) was added to the mixture and stirred at rt for 1 hour. Then the mixture was cooled to 0C and 3-fluoro-4-nitrobenzonitrile (1 .95 ml) was added in portions and stirred for 2 hours. The mixture was poured in water and extracted with DCM. The organic layer was washed with water, dried andconcentrated.Yield: 4.9 g
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 218632-01-0.
