|Section2= |Section3= }} 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 a white, water-soluble solid, 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. It is relatively inexpensive, with 100 grams of analytical grade hydrazine sulfate costing about US$20, and 100 tablets or capsules (60 milligrams hydrazine sulfate) costing US$20 to US$60. Hydrazine sulfate also has a variety of uses in the chemical industry.〔 This salt once attracted attention for its alleged medicinal properties. ==Preparation== The salt is prepared by oxidation of ammonium sulfate with bleach. Hydrazine sulfate easily purified by recrystallization from water. Hydrazine can be reformed by simply raising the pH of a solution of the salt. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydrazine sulfate」の詳細全文を読む スポンサード リンク
