Barbituric acid or malonylurea or 6-hydroxyuracil is an organic compound based on a pyrimidine heterocyclic skeleton. It is an odorless powder soluble in water. Barbituric acid is the parent compound of barbiturate drugs, although barbituric acid itself is not pharmacologically active. The compound was discovered by the German chemist Adolf von Baeyer on December 4, 1864, the feast of Saint Barbara (who gave the compound its namesake), by combining urea and malonic acid in a condensation reaction. Malonic acid has since been replaced by diethyl malonate, as using the ester avoids the problem of having to deal with the acidity of the carboxylic acid and its unreactive carboxylate.

5-hydroxyuracil, also known as dihydropyrimidine-2,4,5(3h)-trione or isobarbituric acid, is a member of the class of compounds known as hydroxypyrimidines. Hydroxypyrimidines are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-hydroxyuracil is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 5-hydroxyuracil can be found in broad bean, which makes 5-hydroxyuracil a potential biomarker for the consumption of this food product. 5-hydroxyuracil is an oxidized form of cytosine that is produced by the oxidative deamination of cytosines by reactive oxygen species. It does not distort the DNA molecule and is bypassed by replicative DNA polymerases. It can miscode for adenine and is potentially mutagenic .
