| Application | N,N-dimethylacetoacetamide is an organic intermediate that can be used to prepare thioamide compounds. As important thiocarboxylic acid derivatives, thioamides have attracted much attention in pharmaceutical synthesis, chemical engineering and related fields. Thioamides and their derivatives have a wide range of applications in analysis, materials, and electrochemistry, not only for the production of polymerization inhibitors, catalysts, stabilizers, pesticides, etc., but also for the production of pharmaceutical raw materials, vulcanizing agents, cross-linking reagents, collectors, etc. |
| Application example | preparation of 3-anilino-n, n-dimethyl-3-oxosubunit thiopropionamide: add 1.62g of phenyl isothiocyanate with a purity of 98%, 1.38g of potassium carbonate with a purity of 99%, 1.29g of N,N-dimethylacetoacetamide with a purity of 98% to 30ml of absolute ethanol with a purity of 99.7%, stir at room temperature for 30min, heat the system to reflux, and stir at room temperature for 1.8h. After completion of the reaction, ethanol was distilled off, after cooling, 10% dilute hydrochloric acid (30ml) was added, and the resulting precipitate was stirred, filtered, washed with water, and dried under vacuum to obtain 3-anilino-n, n-dimethyl-3-oxosubunit thiopropionamide in 88.6% yield (based on N,N-dimethylacetoacetamide). |
