Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 5424-01-1, name is 3-Aminopyrazine-2-carboxylic acid, A new synthetic method of this compound is introduced below., Quality Control of 3-Aminopyrazine-2-carboxylic acid
15 g of 3-aminopyrazine-2-carboxylic acid was added to 200 ml of methanol.Add 10 ml of thionyl chloride, stir overnight at room temperature, and concentrate.200 ml of toluene was added and concentrated to give 18 g of 3-aminopyrazine-2-carboxylic acid methyl ester.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
