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. 81945-73-5, name is 1H-Pyrazol-1-ol, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 81945-73-5
1-Benzyloxy-lH-pyrazole; To a mixture of pyrazol-1-ol (1 g, 11.9 mmol) and /-Pr2NEt (2.02 mL, 11.9 mL) in DCM (15 mL) at 0 0C was added BnBr (4.09 mL, 23.8 mmol). The mixture was allowed to warm up to r.t. and stirred at this temperature for 22 h. The mixture was concentrated in vacuo to afford a yellow paste. The crude product was purified by flash chromatography (silica gel, hexanes/DCM/Et2O (100:0:0 to 80:10:10), Rf 0.23 in hexanes/DCM/Et2O (34:3:3)) to provide the title product as a yellow oil (1.17 g, 56%).
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 81945-73-5.
