General description

Pyridazine is a mono-basic 1,2-diazine compound, which is commonly prepared by the reaction of 1,4-dicarbonyls with hydrazines. Pyridazine ring is found in many herbicides like credazine, pyridatol and many pharmaceutical drugs like cefozopran, olaparib, talazoparib, and cadralazine.

Application

Pyridazine can be used:
  • As a building block to synthesize N-phenyl-4-pyrazolo[1,5-b]pyridazin-3-yl-pyrimidin-2-amine derivatives as GSK-3 inhibitors.
  • As a starting material in the synthesis of pharmacologically important pyrrolo[1,2-b]pyridazine derivatives.
  • To prepare 1-(6-ethoxy-6-oxohexyl)pyridazin-1-ium bromide and 1-(2-bromoacetyl) pyridazinium bromide ionic liquids as corrosion inhibitors of steel under acidic conditions.
