The basicities of some pyridazine derivatives
Journal of the Chemical Society, Perkin Transactions 2, 1972Changes in the basicity of a number of dimethylaminopyridazines, chloropyridazines, and pyridazones have been correlated with substituent constants by use of the Hammett free-energy relationship.

Synthesis of pyrazolo [4,5]pyridazine and isoxazolo [3,4d]pyridazine derivatives
Archives of Pharmacal Research, 1992Arylhydrazones of diethylacetondicarboxylate3 was treated with formaldehyde to give 1-aryl-4,5,6-trihydropyridaine derivatives4a-f Cyclization of compound4a-f by hydroxylamine afforded [3,4d] 1,3,4,5-tetrahydropyridazine derivatives5a-f. Also cyclization of compound4c with semicarbazide gave 1-amidopyrazolo-5-one-1-aryl-3-carboxypyridazine6.

Acid-Induced Multicolor Fluorescence of Pyridazine Derivative
ACS Applied Materials & Interfaces, 2017Smart luminescent materials that are responsive to external stimuli have received considerable attention. Here, we report a new D-A type 1,2-pyridiazine derivative (3,4,5,6-tetrakis(4-methoxyphenyl)pyridazine (TPP)) exhibiting turn-on fluorescence upon acid exposure both in solution and in the solid state.

Synthesis and Biological Activities of Novel Pyridazine Derivatives
Физиология растений, 2016A series of pyridazine derivatives was synthesized and some of them showed a growth stimulatory activity during preliminary screening. Their effects on germination, morphogenesis, peroxidase activity and lignan content were tested on common bean (Phaseolus vulgaris L.) plants.
