Related Products of 1450-93-7, 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. 1450-93-7, name is 1H-imidazol-2-amine sulfate(2:1), This compound has unique chemical properties. The synthetic route is as follows.
2-Aminoimidazole sulfate (659 mg) is dissolved in 0.42 mL of concentrated HCl, 1 mL of water, and 3 mL of acetic acid. The resulting solution is cooled to 0 C. To the solution is added 345 mg of NaNO2 in 1 mL of water dropwise so the internal temperature is maintained below 5 C. The resulting yellow-brown solution is stirred for 30 minutes at 0 C. In a separate flask equipped with a mechanical stirrer a mixture of 1.0 g of 2,2,2-trifluoro-1-(4-pentyl-3,4-dihydroquinoxalin-1(2H)-yl)ethan-1-one, 0.82 g of sodium acetate and 3 mL of acetic acid is cooled to 0 C. To this slurry is added the diazonium solution slowly while stirring. After the addition is complete, the resulting red suspension is stirred for 1 hour at 0 C. The dark reaction mixture is poured into a beaker containing 10 g of ice. Aqueous NaOH (20%) is added to the suspension slowly until pH 6.5 is reached. The mixture is filtered and brick red solid is collected. The crude (E)-1-(7-((1H-imidazol-2-yl)diazenyl)-4-pentyl-3,4-dihydroquinoxalin-1(2H)-yl)-2,2,2-trifluoroethan-1-one is dried and used in the next step without further purification (0.94 g).
The chemical industry reduces the impact on the environment during synthesis 1H-imidazol-2-amine sulfate(2:1). I believe this compound will play a more active role in future production and life.
