Application of 3524-32-1, The chemical industry reduces the impact on the environment during synthesis 3524-32-1, name is 5-Amino-1,3-dimethylpyrazole, I believe this compound will play a more active role in future production and life.
To a solution of 11.1 g (0.1 mol) of 5-amino-1,3-dimethylpyrazole, obtained in the above step, in 125 cm3 of absolute ethanol were added dropwise 1cm3 of 12 N hydrochloric acid and then 13.5 cm3 of isoamyl nitrite, at 0 C. The solution was subsequently warmed to and left at room temperature for 4 hours. The reaction medium was then filtered on a sinter funnel and the precipitate obtained was washed with 100 cm3 of isopropyl ether. After drying under vacuum at room temperature, 7.5 g of 5-amino-1,3-dimethyl-4-nitroso-pyrazole were obtained in the form of an orange-coloured solid, the melting point of which was from 169 to 171 C.
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, 5-Amino-1,3-dimethylpyrazole, other downstream synthetic routes, hurry up and to see.
