Tartronic acid or 2-hydroxymalonic acid is a dicarboxylic acid with the structural formula of HOOCCH(OH)COOH.

Its derivative, 2-methyltartronic acid, is isomalic acid.


Tartronic acids are best known as a reactant in the catalytic oxidation with air to form mesoxalic acid, another type of hydroxydicarboxylic acid.[1]
