Diazine

Organic compound (C4H4N2); benzene with two CH groups replaced by N

In organic chemistry, diazines are a group of organic compounds having the molecular formula C4H4N2. Each contains a benzene ring in which two of the C-H fragments have been replaced by isolobal nitrogen.[1] There are three structural isomers:

  • pyridazine (1,2-diazine)
  • pyrimidine (1,3-diazine)
  • pyrazine (1,4-diazine)
