7716-66-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3-Chlorobenzo[d]isothiazole, cas is 7716-66-7,the isothiazole compound, it is a common compound, a new synthetic route is introduced below.
An eggplant type flask was charged with 3-chloro(1,2-benzisothiazole) (14 g, 200 mmol) and piperazine anhydride (6.8 g, 40 mmol) and heated at 125 ¡ã C. for 24 hours. After completion of the reaction, 52 ml of ice- In addition, quench, add 3.2 g of 50percent NaOH solution, stir for 5 min, extract with CH 2 Cl 2 50 ml * 3, wash the organic layer with 50 ml each of ice water * 2, 50 ml * 2 of saturated brine * 2 and anhydrous MgSO4 To give 4- (1,2-benzisothiazol-3-yl)piperazine.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 3-Chlorobenzo[d]isothiazole, 7716-66-7
