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. 3920-50-1, name is Pyrazole-3-carboxaldehyde, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 3920-50-1
1.18 g (20 mmol) of hydroxylamine hydrochloride, 1.63 g (20 mmol) of sodium acetate and 40 ml of ethanol were added to a 100 ml three-necked flask, and 0.96 g (10 mmol) of 3-formaldehyde pyrazole was added thereto with stirring. The temperature was raised to 50 C and the reaction was carried out for 2 h. After the reaction, a milky white turbid liquid was obtained, which was cooled to room temperature, filtered, and the filtrate was evaporated to give an oily viscous solid. Dissolved in 50 ml of water, The organic phase was dried over anhydrous sodium sulfate and filtered. The filtrate was evaporated to dryness to give a pale yellow viscous solid, 0.94 g. The yield was 85.3%.
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 3920-50-1.
