Pyrimidines and pyrimidine derivatives are compounds containing a pyrimidne ring, which is a six-member aromatic heterocycle which consists of two nitrogen atoms (at positions 1 and 3) and four carbon atoms. Pyrimidine exists as a solid, possibly soluble (in water), and a moderately basic compound (based on its pKa) molecule. Pyrimidine exists in all living organisms, ranging from bacteria to humans. 1,3-Diazin 1,3-Diazine m-Diazine Metadiazine Pyrimidin Pyrimidine base 1,3-Diazabenzene Miazine PY PYR Pyrimidine dimer C4H4N2 80.088 80.037448138 pyrimidine pyrimidine 289-95-2 C1=CN=CN=C1 InChI=1S/C4H4N2/c1-2-5-4-6-3-1/h1-4H CZPWVGJYEJSRLH-UHFFFAOYSA-N belongs to the class of organic compounds known as pyrimidines and pyrimidine derivatives.
