Applications · 2 items

UsesHydroxyacetone is a chemical reagent used in various organic chemical reactions. It is a component of the Mannich reaction, amino acid caalyzes direct asymmetric aldol reactions. In the pharmaceutical setting, this compound is used in the synthesis of imidazoles acting as potent and orally active antihypertensive agents. It is also used in the syntheses of 2-oxo-propionaldehyde, imidazoles, polyols, acrolein, dyes and skin tanning agents. It yields (R)-1,2-propanediol upon reduction of hydroxyacetone in the presence of a microbial cell catalyst.

General DescriptionHydroxyacetone (Acetol) is important for the manufacture of polyols, acrolein, dyes and skin tanning agents. It undergoes asymmetric reduction to yield (R)-1,2-propanediol in the presence of microbial cell catalyst.
