The reaction between the hydroxyl radical (OH) and triose reductone (2,3-dihydroxy-2-propenal) in an aqueous solution has been studied by spectrophotometric pulse radiolysis. The OH radical adds to triose reductone (TRH<SUB>2</SUB>) to form the transient OH adduct (TRH(OH)<SUP>−·</SUP>) with an absorption maximum at 398 nm, ε=3150 M<SUP>−1</SUP> cm<SUP>−1</SUP> (1 M=1 mol dm<SUP>−3</SUP>) in a neutral solution. The OH adduct decays by second-order kinetics in the pH range 2–12. The rate constants for the reactions of the OH radical with dissociated and undissociated triose reductone are 1.4×10<SUP>10</SUP> M<SUP>−1</SUP> s<SUP>−1</SUP> and 9.9×10<SUP>9</SUP> M<SUP>−1</SUP> s<SUP>−1</SUP>, respectively. The dependence of the transient absorption on the pH shows that the OH adduct has a p<I>K</I><SUB>a</SUB> value of 4.7.
