Reference of 4263-52-9, 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. 4263-52-9, name is Sodium 2-bromoethanesulphonate, This compound has unique chemical properties. The synthetic route is as follows.
Synthesis of intermediate II (1-delta-sulphoethyl,-2,3,3-trimethyl-5-sulphonamido indolenininium inner salt); [Show Image] 150 g of 2-bromoethanesulfonic acid sodium salt, Fluka, 1,5 1 of ethanol are mixed together, the mixture is then cooled to 5C and 29,2 g of hydrochloric acid gas are bubbled through the mixture. After that, the mixture is brought back to RT and left under stirring for 4 hours. After filtration of sodium chloride, the mixture is concentrated to dryness under vacuum. 1,6 g of 2-bromoethanesulfonic acid, obtained with the method reported above, 1,3 g of intermediate I, 0,7 g of triethylamine and 5 ml of butirronitrile are mixed together and heated to reflux for 20 hours. The mixture is then cooled to rrom temperature and 15 ml of acetone are added. The solid product is vacuum filtered and washed with methanol and acetone. The reaction yield is 50%.
The chemical industry reduces the impact on the environment during synthesis Sodium 2-bromoethanesulphonate. I believe this compound will play a more active role in future production and life.
