75884-70-7, 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. 6-Bromophthalazin-1(2H)-one, cas is 75884-70-7,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
Step a 6-Bromo-2-(3-carboxypropyl)phthalazin-1(2H)-one To a slurry of 56 gm 6-bromophthalazin-1(2H)-one (0.25 mole) in 600 ml DMSO was added 110 ml 45% KOH followed by 58.5 gm ethyl 4-bromobutyrate. The temperature of the mildly exothermic reaction was moderated with a water bath (ca. 25 C.) and was stirred for 20 hours. Ethanol (750 ml) was added, then the mixture was acidified with 125 ml concentrated HCl, diluted with 2500 ml water over about 30 minutes, stirred an additional 30 minutes, filtered, washed with water and isopropanol and dried. The product weighed 63.6 gm. A tlc of the product showed product, Rf =0.43 plus a trace of starting material, Rf =0.63.
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 6-Bromophthalazin-1(2H)-one, 75884-70-7
