|Section2= |Section3= }} Dioxosuccinic acid or dioxobutanedioic acid is an organic compound with formula C4H2O6 or HO-(C=O)4-OH. Removal of two protons from the molecule would yield the dioxosuccinate anion, C4O62− or (O-(C=O)4-O)2−. This is one of the oxocarbon anions, which consist solely of carbon and oxygen. The name is also used for salts containing that anion, and for esters with the () moiety. Removal of a single proton would result in the monovalent anion hydrogendioxosuccinate, C4HO6 − or (HO-(C=O)4-O)−. ==Occurrence== Dioxosuccinic acid is one of the acids occurring naturally in wine, from the oxidation of tartaric acid via dihydroxyfumaric acid.〔 By Ján Farkaš, Beatrix Farkas (1988), ''Technology and Biochemistry of Wine''.CRC Press, 744 pages.
