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. 55557-52-3, name is 3-Chloropyrazine-2-carbonitrile, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of 3-Chloropyrazine-2-carbonitrile
3-chloropyrazine-2-carbonitrile (32 g) was dissolved in 300 ml of acetic acid and 14 g of Raney nickel in 50% slurry,Slowly add to the above solution, pass 4.5 bar of hydrogen, and stir overnight at room temperature.Filtered through diatomaceous earth, and the filtrate was spin-dried. The ethyl acetate was taken with water to obtain a solid. The solid was dissolved in 50 C ethyl acetate.A hydrogen chloride gas was passed into the ethyl acetate solution, and a solid was precipitated, filtered, and the filter cake was washed with ethyl acetate.Drying under vacuum at 50 C gave 23 g (3-chloropyrazin-2-yl) methylamine.hydrochloride.
According to the analysis of related databases, 55557-52-3, the application of this compound in the production field has become more and more popular.
