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. 5334-40-7, name is 4-Nitro-1H-pyrazole-3-carboxylic acid, A new synthetic method of this compound is introduced below., Product Details of 5334-40-7
20 g of 4-nitropyrazolo-l-carboxylic acid (1) (127.32 mM) as a starting material was drop wisely added to the reaction solution dissolving 11.10 ml of acetyl chloride (381.96 mM) in 350 ml of methanol to react together and finally 23.69 g of methyl- 4-nitro-lH-pyrazole-3-carboxylate hydrochloride was obtained (yield: 90percent).
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.
