1,3-Dihydroxyacetone dimer is used as a catalytic agent and petrochemical additive. It is also used as a building block in organic synthesis. Further, it serves as a reagent in three-carbon nucleophilic or electrophilic component in various reactions.
In solid state, exists predominantly as trans-2,5-dihydroxy-1,4-dioxane-2,5-dimethanol (structure and CAS registry number as shown). On melting or in solution, mainly dissociates to monomeric 1,3-dihydroxyacetone [96-26-4]: J. Mol. Struct., 35, 85 (1976).
