Metabolite Identification
Common NamePyrimidine
DescriptionPyrimidine, also known as pyrimidine base or 1,3-diazin, belongs to the class of organic compounds known as pyrimidines and pyrimidine derivatives. 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.
