isomeric with two other diazine (C4H4N2) rings, pyrimidine and pyrazine. Pyridazines are rare in nature, possibly reflecting the scarcity of naturally occurring

other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) and pyridazine (nitrogen atoms at the 1 and 2 positions). In nucleic acids, three types

with hydrazines afford dihydropyridazines, which can be converted to pyridazines. para-quinone, C4H4(CO)2, is the parent of a large family of 1,4-diketones

conversion of hydrazine to heterocyclic rings such as pyrazoles and pyridazines. Examples of commercialized bioactive hydrazine derivatives include cefazolin

between a chloro-substituted pyridazine and the primary amine group of a morpholine derivative. The required pyridazine can be made by the reaction of
