4-Hydroxypyrimidine Usage And Synthesis

Description

Pyrimidone(4-Hydroxypyrimidine) is the name given to either of two heterocyclic compounds with the formula C4H4N2O: 2-pyrimidone and 4-pyrimidone. The compounds can also be called 2-hydroxypyrimidine or 4-hydroxypyrimidine respectively, based on a substituted pyrimidine, or 1, 3-diazine, ring. 4-pyrimidinone is an important bioactive molecule with various biological activities such as anti-virus, anti-tumor, induction of interferon production and immune regulation.

Chemical Properties

white to slightly yellow powder

Hazard

Causes skin irritation. Causes serious eye irritation. May cause respiratory irritation.

Enzyme inhibitor

This hygroscopic pyrimidine, also known as 4-hydroxypyrimidine and 4- pyrimidinol (FW = 96.09 g/mol), inhibits both hypoxanthine(guanine) and xanthine phosphoribosyltransferases.
