1121-79-5, 3-Chloro-6-methylpyridazine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A. To a mechanically stirred solution of 3-chloro-6-methylpyridazine (155.6 mmol) in 140 mL of concentrated sulfuric acid, finely powdered potassium dichromate (55.40 g) was added slowly, the temperature being kept below 50 C. When the addition was complete, stirring was continued for another 4 hours at 50 C. The viscous, dark green liquid was then cooled and crushed ice was added cautiously. The reaction mixture was extracted with ethyl acetate (6*400 mL). The ethyl acetate extracts were combined, dried over anhydrous Na2SO4. The solvent was concentrated in vacuo to yield slightly red colored 6-chloropyridazine-3-carboxylic acid (106.6 mmol). This material was used for next reaction without further purification. Yield 69%. m.p. 145 C. (dec). 1H NMR (300 MHz, DMSO-d6) delta 13.1, 8.20, 8.05., 1121-79-5
As the paragraph descriping shows that 1121-79-5 is playing an increasingly important role.
