Description

Hydrazine sulfate is the salt of hydrazine and sulfuric acid. It is a white, water-soluble salt 
of the cation hydrazinium and the anion bisulfate, giving the formula (N2H5)HSO4. 
It is prepared by treating an aqueous solution of hydrazine with sulfuric acid. 

It has a number of laboratory uses in analytical chemistry and the synthesis of organic 
compounds. Hydrazine sulfate is used as a precursor to hydrazine.

For some applications, this salt is preferred over pure hydrazine because it is nonvolatile and less
susceptible to atmospheric oxidation on storage. 
These same properties make it the preferred form of hydrazine for dietary supplements and pharmaceutical 
trials. Hydrazine sulfate also has a variety of uses in the chemical industry.

This salt once attracted attention for its alleged medicinal properties.

[Industrial uses]
Hydrazine sulfate also has a variety of uses in industrial chemistry, including as a chemical intermediate, as a catalyst in making fibers out of acetate, as a fungicide, antiseptic, in the analysis and synthesis of minerals and testing for arsenic in metals.
