Antihypertensive aryl pyrazolo[4,3-c]pyridazinones

The compounds are aryl-pyridazinone derivatives, e.g., 1-methyl-5-(2'-fluoro-5'-trifluoromethylphenyl)-1H-pyrazolo [4,3-c]pyridazin-6(5H)-one. They are useful as antihypertensives and are prepared by treating a hydrazinopyridazinone with a dialkylamino di

5-Hydrazinopyridazin-3(2H)-ones

Substituted 5-hydrazinopyridazin-3(2H)-ones, e.g., 4-chloro-2-(3-trifluoromethylphenyl)-5-(1-methylhydrazino)-pyridazin-3(2H)-one or 4-chloro-2-(2-fluoro-5-trifluoromethylphenyl)-5-(1-methylhydrazino)-pyridazin-3(2H)-one, are prepared by treating halogena
