BARBITURIC ACID FOR SYNTHESIS
SKU: RXSOL-60-6604-005
BARBITURIC ACID FOR SYNTHESIS: 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.
Application
Barbituric acid has been utilized in the design and synthesis of diverse types of heterocyclic and carbocyclic compounds and considered as an important building block in organic synthesis. There is a wide range of multicomponent reactions that include barbituric acid as starting material.
Dosage
Barbituric acid has been prepared by the action of phosphorus oxychloride on malonic acid and urea;1 by treating an acetic acid solution of urea and malonic acid with acetic anhydride;2 from diethyl malonate and urea using sodium ethoxide as a condensing agent;3 and from diethyl malonate and the sodium derivative
