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.

This salt is sometimes preferred over pure hydrazine because it is nonvolatile and less susceptible to atmospheric oxidation on storage. These properties have made it attractive for a variety of uses in the chemical industry and at some point as an alternative medical treatment.

The salt is prepared by oxidation of ammonium sulfate with bleach. Hydrazine sulfate is purified by recrystallization from water.

If free base hydrazine is available, its solutions react with sulfuric acid to give the salt.

Known by the trade name Sehydrin, it is a chemical compound that has been used as an alternative medical treatment for the loss of appetite (anorexia) and weight loss (cachexia), which are often associated with cancer. Hydrazine sulfate has never been approved in the United States as safe and effective in treating any medical condition, although it is marketed as a dietary supplement. It is also sold over the Internet by websites that promote its use as a cancer therapy. The active ingredient is hydrazine, and the sulfate component is present to aid in formulation.
