Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Uracil exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Uracil exists in all living species, ranging from bacteria to humans. Uracil is a potentially toxic compound. 2,4(1H,3H)-Pyrimidinedione 2,4-Dioxopyrimidine 2,4-Pyrimidinedione U Ura Urazil 2,4-Dihydroxypyrimidine 2,4-Pyrimidinediol Hybar X Pirod Pyrod C4H4N2O2 112.0868 112.027277382 1,2,3,4-tetrahydropyrimidine-2,4-dione uracil 66-22-8 O=C1NC=CC(=O)N1 InChI=1S/C4H4N2O2/c7-3-1-2-5-4(8)6-3/h1-2H,(H2,5,6,7,8) ISAKRJDGNUQOIC-UHFFFAOYSA-N belongs to the class of organic compounds known as pyrimidones.
