| Application | N,N'-dimethylethylenediamine is an amine compound and can be used as a pharmaceutical intermediate. N,N-dimethyl ethylenediamine is an important fine chemical product. As an important pharmaceutical intermediate, it can be used to synthesize anti-tumor drugs thioxanthone (thioxanthenone), carbamoyl fish vine, anti-arrhythmic drug procainamide (procainemide), local anesthetic dibukaine (dibucain), antihistamine Hytramine (neo- hetranine), anticholinesterphthalein drug Ambeguanide (I. e. enzyme-yining), cefazolin sodium (Pioneer No. 5), etc. It is used in agriculture to synthesize flower inducers. It is also used as a series of additives (such as fixing agent, wetting agent, fiber softener and antistatic agent, BCH), reactive cationic dye intermediates, ion exchange resins and epoxy resin curing agents. |
| prepare | ethanolamine as the starting material, and react with human hydrogen chloride gas in ethanol medium to obtain ethanolamine chloride with a yield of 52%; The obtained product reacts with thionyl chloride to obtain chloroethylamine chloride with a yield of 71 .4%; The obtained product is then reacted with dimethylamine to obtain a 75%-purpose product after treatment. If ethanolamine is used, the total yield is 27.8%. |
| Use | Used in organic synthesis or as a pharmaceutical intermediate |
