General description

Products of reaction of methyl iodide with 4-methylpyridazine has been investigated by NMR spectra[1]. Solvent free oxidation of 4-methylpyridazine by acetyl peroxyborate, peracetic acid and hydrogen peroxide has been reported[2].

Application

4-Methylpyridazine was used in the preparation of series of novel pyridazine derivatives structurally related to bipyridine cardiotonics[3].
