Anwendungen

Hydroxyacetone is used as a reagent in organic chemical reactions. It also serves as a component for Mannich reaction and aldol reactions. 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.

Bemerkungen

Store in cool place. Air sensitive and hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong acids.
