Barbituric acid (Cat No.: R048189) is a heterocyclic organic compound with the formula C4H4N2O3. It consists of a pyrimidine ring with two keto groups and one enolizable hydrogen, making it a versatile scaffold in organic synthesis. While barbituric acid itself has no central nervous system activity, it serves as the parent structure for barbiturate drugs, which are known for their sedative, hypnotic, and anesthetic effects. It is synthesized via the condensation of malonic acid and urea and is widely used in medicinal chemistry.
