| Use | hydroxyacetone is a chemical reagent used in various organic chemical reactions. It is a component of the Mannich reaction, where amino acids catalyze the direct asymmetric aldol reaction. In the pharmaceutical field, the compounds are useful in the synthesis of imidazole compounds which are useful as oral antihypertensive agents. intermediates in organic synthesis. |
| biological activity | Hydroxyacetone is an endogenous metabolite. |
| production method | potassium hydroxide, anhydrous methanol and ethyl formate were refluxed for 2H to prepare a methanol solution of potassium formate. The mixture was heated to reflux with bromoacetone and reacted for 16H. The reaction was cooled to 0 ℃, potassium bromide was filtered off, and the filtrate was distilled to collect 40-43 ℃(1.6kPa) fractions to obtain hydroxyacetone, yield 54-58%. |
