Category: 78593-33-6

While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. 78593-33-6. Introduce a common compound, CAS is 78593-33-6, Name is 3-Bromocinnoline, belongs to cinnolinecompound.

Starting material 1-A (11.8 g, 40 mmol), starting material 1-B (16.7 g, 80 mmol), CuI (3.8 g, 20 mmol), potassium carbonate (11.1 g, 80 mmol), and 1-methyl-1H-imidazole (3.3 g, 40 mmol) were added to 250 ml of toluene, and then, the mixture was refluxed while stirring under a nitrogen atmosphere for 7 days. Then, the reaction mixture was cooled to room temperature, 300 ml of water was added to isolate the organic layer, and the water layer was extracted twice with 250 ml of dichloromethane. The extracted organic layer was stirred with MgSO4 to remove water therefrom, and the organic layer was filtered and evaporated under reduced pressure. The resulting solid was subjected to column chromatography using, as an eluent, dichloromethane and normal hexane to obtain 5.6 g of Intermediate 1-C at the yield of 33%. MS (MALDI-TOF) m/z: 424 [M]+

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. Introduce a common compound, CAS is 78593-33-6, Name is 3-Bromocinnoline, belongs to cinnoline 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 50ml of dimethylsulphoxide was stirred and heated at -20 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%
