Barbituric acid (CAS NO.67-52-7) was discovered by the German chemist Adolf von Baeyer on 4. December 1864—the feast of St Barbara and therefore the name given to the compound—by combining urea and malonic acid in a condensation reaction. and The first to be used in medicine was barbital (Veronal) starting in 1903, and the second, phenobarbitone a.k.a. phenobarbital was first marketed in 1912.
Barbituric acid (CAS NO.67-52-7) is used in synthesis of riboflavin.
