Tartronic acid or 2-hydroxymalonic acid is an organic compound with the structural formula of HOHC(CO2H)2. This dicarboxylic acid is related to malonic acid. It is a white solid. It is produced by oxidation of glycerol:
- HOCH2CH(OH)CH2OH + 2 O2 → HO2CCH(OH)CO2H + 2 H2O
Glyceric acid HOCH2CH(OH)CO2H is an intermediate.
Its derivative, 2-methyltartronic acid, is isomalic acid.
