3,6-Dihydroxy-4,5-dimethylpyridazine Usage And Synthesis

Uses

4,5-Dimethylpyridazine-3,6-diol is a useful research chemical.

Uses

3,6-Dihydroxy-4,5-dimethylpyridazine can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development processes and chemical production processes.

Synthesis

Hydrazine hydrochloride (58 g, 552 mmol) is dissolved in hot water (300 mL) and dimethyl maleic anhydride (58 g, 460 mmol) is added in portions and the suspension stirred at reflux for 16 h. The suspension is cooled down to room temperature and the precipitate is filtered, washed with water and dried at 40° C. under vacuum to yield 4,5-dimethyl-1,2-dihydro-pyridazine-3,6-dione (36) (64 g, 99%).
