78593-33-6,The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a downstream synthesis route of the compound 78593-33-6
(a) 3-(4-Hydroxybenzenesulphonyl)cinnoline A mixture of 2.1 g (0.01 mol) of 3-bromocinnoline, 6.6 g (0.02 mol) of sodium 4-tosyloxybenzenesulphinate and 50 ml of dimethylsulphoxide was stirred and heated at 120 C. for 24 hours. The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained. Yield: 10.2%
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 78593-33-6.
