Chemical properties of DMPUs:

Due to the strong electron absorption effect of carbonyl group in its structure, it is an aprotic polar solvent with high boiling point, high flash point and low melting point. It is convenient to use in filtration, distillation, solvent extraction and other process operations. Extremely low toxicity, negligible harm to human body, but also reduce environmental pollution; Because it has a strong solubility, can dissolve organic matter, inorganic matter, resin, polymer, and a variety of reagents with activation properties, but also with other high boiling point solvents miscible; Has excellent stability, in hot alkali and acid conditions are very stable, but also has water resistance and light, oxygen stability. Therefore, the application of DMPU in organic chemical reaction can promote the dissolution of reactants, speed up the reaction speed, improve the reaction yield, and replace more toxic solvents.

Application:

Application of DMPUs in pharmaceutical preparations: The skin of an organism is a physiological barrier that prevents the entry of substances outside the body, so topical preparations need to include solvents that can promote skin absorption. This solvent should meet the following needs: active drug groups can quickly and reliably reach the damaged site: does not stimulate the skin, non-toxic; Keep stable for a long time. Dmpus can dissolve a variety of drugs and have little toxicity to the human body, which meets the above requirements, so it can be used as drug excipients. The combination of DMPU and other excipients and drugs can promote the dissolution and mixing of the drug, enhance the stability and transdermal absorption ability of the drug, and prolong the action time of the drug.

Advanced use

1. Practice has proved that the comprehensive performance of DMPU in fine chemical production has been greatly improved. In antibiotic production and other aspects, DMPU is more suitable for synthetic production due to its high dielectric constant and boiling point.

2, can be used in industrial production, instead of carcinogenic HMPA, and has good green environmental protection benefits.
