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. 19745-07-4, name is 2,5-Dichloropyrazine, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C4H2Cl2N2
EXAMPLE 1a 1-(5-Chloro-2-pyrazinyl)piperazine A mixture of 2,5-dichloropyrazine (14.9 g, 0.1 mol), piperazine (50.5 g, 0.59 mol), acetone (22.5 ml), water (20 ml) and concentrated aqueous HCl (1.8 ml) was heated at reflux for 3 hr. The reaction mixture was cooled, diluted with water, filtered and the acetone was removed by distillation. The aqueous solution was then extracted thrice with chloroform. The combined extracts were washed twice with water, dried (Na2 SO4) and evaporated to dryness to afford 7.3 g of solid, m.p. 98°-102°. J. K. Boissier et al., J. Med. Chem., 6, 541 (1963) report a m.p. of 101° C.
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 19745-07-4.
