Application of 3469-69-0<\/a>, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 3469-69-0, name is 4-Iodopyrazole, This compound has unique chemical properties. The synthetic route is as follows.<\/p>\n

General procedure: Step 1: 1-methyl-4-iodopyrazole 1H-4-iodopyrazole (20 g), potassium carbonate (28.45 g) and acetone (120 mL) were added into a round bottomed flask (250 mL) and agitated for 10 min. Then iodomethane (17.56 g) was added and the mixture was agitated at room temperature over night. After that, the mixture was filtrated and concentrated, the residue was recrystallized from n-hexane to prodce 1-methyl-1H-4-iodopyrazole (15 g) as white acicular crystal. 1H-NMR (300Hz, CDCl3) delta: 7.48 (s, 1H), 7.40 (s, 1H), 3.92 (s, 3H).<\/p>\n

The chemical industry reduces the impact on the environment during synthesis 4-Iodopyrazole. I believe this compound will play a more active role in future production and life.<\/p>\n
