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.] |
