Pyrimidone is the name given to either of two heterocyclic compounds with the formula C4H4N2O: 2-pyrimidone[1] 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.
Applications
Energy storage
Chemists at UC Santa Barbara have determined that pyrimidone can be used for reversible, stable, long term thermal energy storage with an energy density of 1.6 MJ/kg[2], approximately double that of a lithium ion battery.
Derivatives
Derivatives of pyrimidone are the basis of many other biological molecules, including:
- Nucleobases, such as cytosine
- Barbiturates, such as metharbital
- Antiulcer drugs including temelastine, icotidine, donetidine, and lupitidine.
