19353-92-5 - Reference Information
| Use | p-dimethylaminobenzoyl hydrazide is an organic intermediate. |
| preparation | p-dimethylaminobenzoyl hydrazide can be prepared from ethyl p-aminobenzoate as raw material, and then obtained by hydrolysis with hydrazine hydrate. There are reports that it can be used to prepare a permanently charged hydrazine sugar marker. A, weigh 1g of ethyl p-aminobenzoate in a two-mouth round bottom flask, add 40ml of acetone to dissolve, then add 3.6g of anhydrous potassium carbonate and 14.1g of methyl iodide, stir and reflux at 80 ℃ under the protection of nitrogen for 24 hours, filter the reaction liquid, take the filtrate, extract with dichloromethane, remove water with magnesium sulfate for the organic phase, evaporate and concentrate after filtering out magnesium sulfate, and separate and purify the product by chromatography column (mobile phase dichloromethane: methanol = 20:1), product A is obtained. B, adding 80% hydrazine hydrate to product a according to a molar ratio of 1:20, 95% ethanol as solvent, refluxing reaction at 90 ℃ under nitrogen protection. after the reaction is completed, chromatography column purification (mobile phase dichloromethane: methanol = 20:1) obtains product B, I .e. p-dimethylaminobenzoyl hydrazide. |
