Adding a certain compound to certain chemical reactions, such as: 876343-24-7, name is 1-Ethyl-1H-pyrazol-4-amine, 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 876343-24-7, SDS of cas: 876343-24-7
Example 4. Compounds of formula IV[0077] 4-Isothiocyanato-l -methyl- lH-pyrazole (Compound 1012), 4-isothiocyanato-l,3- dimethyl-lH-pyrazole (Compound 1013), and l-ethyl-4-isothiocyanato-lH-pyrazole (Compound 1014) were prepared from 1 -methyl- lH-pyrazol-4-amine, l,3-dimethyl-lH-pyrazol-4-amine (from Matrix Chemical Co.), and 1 -ethyl- lH-pyrazol-4-amine (from Oakwood Products), respectively, by reacting the pyrazolamine with thiophosgene at O0C in the presence of pyridine.CH,[1012] [1013] [1014]
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, 1-Ethyl-1H-pyrazol-4-amine, other downstream synthetic routes, hurry up and to see.
