1. barbituric acid

   Barbituric acid is an organic compound that is considered to be the parent compound of barbiturate drugs, which are commonly used for sedation and as anesthetic agents. It is a pyrimidine derivative with the chemical formula C4H4N2O3. This crystalline substance was first synthesized in 1864 and forms the basis for a range of other chemically related substances. Despite being the fundamental structure of barbiturates, barbituric acid itself does not have any sedative or anesthetic properties.

1. Barbituric acid

   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, 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 Malonic acid has since been replaced by diethyl malonate, as using the ester avoids the problem of having to deal with the acidity of the carboxylic acid and its unreactive carboxylate. The α-carbon has a reactive hydrogen atom and is quite acidic even for a diketone species because of the additional aromatic stabilisation of the carbanion. Using the Knoevenagel condensation reaction, barbituric acid can form a large variety of barbiturate drugs that behave as central nervous system depressants. Barbituric acid is used in synthesis of riboflavin. As of 2007, more than 2550 barbiturates and related compounds have been synthesised, with 50 to 55 in clinical use around the world at present. The first to be used in medicine was barbital starting in 1903, and the second, phenobarbitone a.k.a. phenobarbital was first marketed in 1912.
