Share a compound : 4-Nitro-1H-pyrazole

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Nitro-1H-pyrazole, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 2075-46-9, name is 4-Nitro-1H-pyrazole, belongs to pyrazoles-derivatives 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 2075-46-9, 2075-46-9

The 4-amino-l -methyl- lH-pyrazole used as a starting material was prepared as follows :-Dimethyl sulphate (5 ml) was slowly added to a stirred solution of 4-nitropyrazole (2 g) in IN aqueous sodium hydroxide solution (20 ml) that had been warmed to 30C and the resultant mixture was stirred at that temperature for 48 hours. The mixture was cooled to ambient temperature and the precipitate was isolated, washed with cold water and dried under vacuum. There was thus obtained l-methyl-4-nitro-lH-pyrazole (1.5 g); 1H NMR: (DMSOd6) 3.91 (s, IH), 8.24 (s, IH), 8.85 (s, IH).
