Maleic hydrazide CAS:123-33-1 is obtained by reaction of with 
It was prepared by the reaction of butanedioic anhydride (or butanedioic acid)
with hydrazine sulfate at 35 ~ 56ºC.

Maleic hydrazide CAS:123-33-1 can be used as plant growth regulator, and biochemical research.
Maleic hydrazine is a selective herbicide and a temporary plant growth inhibitor.
The agents can enter the plant through the leaf cuticle, reduce photosynthesis,
osmotic pressure and evaporation, and strongly inhibit bud growth.Used to prevent potato,
onion, garlic and radish from developing Chemicalbook buds during storage period,
and can inhibit crop growth and prolong flowering. It can also be used for weeding non-arable land.
The tautomerism of the product is 3, 6-dihydroxypyridazine (3, 6-dihydroxypyridazine).

Maleic hydrazide CAS:123-33-1 could be supplied in commercial size with competitive price.
