Dihydroxymalonic acid is an organic compound with formula C3H4O6 or HO-(C=O)-C(OH)2-(C=O)-OH, found in some plants such as alfalfa and in beet molasses.[2]
The compound is also called dihydroxymesoxalic acid and dihydroxypropanedioic acid. It can be viewed as a hydrate derivative of mesoxalic acid, and is often called mesoxalic acid monohydrate and similar names.[3] This compound is unusual in containing stable geminal hydroxy groups.
Dihydroxymalonic acid is a water-soluble white solid. It crystallizes in deliquescent prisms that melt between 113 °C and 121 °C without loss of water.[4] It has been used in medical research as a hypoglycemic agent[5] and was patented in the United States in 1997 as a fast-acting antidote to cyanide poisoning.[6]
