4-Pyrimidinol Usage And Synthesis

Chemical Properties

Light yellow crystalline

Uses

4(3H)-Pyrimidinone, is a derivative of Pyrimidone, that can be used as a building block for the preparation of many other biologically molecules, such as Metharbital. It has also been shown to present in the GU "wobble" pair.

Safety Profile

Mutation data reported. When heated to decomposition it emits toxic vapors of NOx

Purification Methods

It crystallises from *benzene or ethyl acetate. The picrate has m 164-166o and crystallises from EtOH [Brown et al. J Chem Soc 4035 1955, Beilstein 24 III/IV 171.]
