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. 694-31-5, name is 1,5-Dimethyl-1H-pyrazole, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 1,5-Dimethyl-1H-pyrazole
General procedure: To a solution of pyrazole 1a (50.0 g, 0.45 mol) in pyridine (200 mL,2.6 mol) cooled to 0 C (CF3CO)2O (69.5 mL, 0.50 mol) was added dropwise. The mixture was stirred at r.t. for 12 h. H2O (1000 mL) was added. The formed suspension was washed with CH2Cl2 (3 × 500 mL). The organic layer was dried (Na2SO4), filtered, and evaporated under vacuum. The residue was purified by vacuum distillation (bp 107-110 C/26.7 mbar) to afford pure 2a (78.6 g, 0.38 mmol, 84%) as a yellowish liquid.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 694-31-5.
