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.
Acetol esters, formed by DCC coupling, have been employed as a means of carboxyl protection, stable to acid and hydrogenolysis, in peptide synthesis. They can be cleaved with TBAF in THF: Tetrahedron Lett., 33, 3193 (1992).
