The important role of 7716-66-7

The chemical industry reduces the impact on the environment during synthesis,7716-66-7,3-Chlorobenzo[d]isothiazole,I believe this compound will play a more active role in future production and life.

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.

3-Chlorobenzo[d]isothia-zole (300 mg, 3.0 mmol) was dissolved in propane- 1,3 -diamine (3 mL) and heated at 8O0C for 3 h. The reaction mixture was cooled to room temperature, poured into water and extracted with ethyl acetate. The organic extract was dried over anhydrous sodium sulfate, filtered and the filtrate concentrated under reduced pressure to yield ^-(benzotdJisothiazol-S-ytypropane- 1,3-diamine as a yellow solid, (530 mg). 1H NMR (300 MHz, CDCl3): 7.8 (m, IH), 7.7 (m, IH), 7.5 (m, 2H), 7.3 (m, IH), 3.7 (m, 2H), 2.9 (t, 2H), 1.9 ppm (m, 2H).
