Adding a certain compound to certain chemical reactions, such as: 19745-07-4, name is 2,5-Dichloropyrazine, belongs to pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 19745-07-4, COA of Formula: C4H2Cl2N2
Into a 250 ml 3-necked round bottom flask, was placed 45% hydriodic acid (60 ml). To this was added sodium iodide (25 g, 0.17 mol). To the mixture was added XV-B-86 (10.5 g, 0.07 mol). The resulting solution was allowed to react at room temperature. Adjustment of the pH to >8 was accomplished by the addition of 20 g NaOH in 50 g ice to afford XV-C-86.
