硫酸肼^[2]是聯氨與硫酸生成的鹽類，指N₂H₅HSO₄和N₂H₆SO₄兩種物質，常寫作N₂H₄·H₂SO₄。

N₂H₆SO₄遇水完全水解，產生N₂H₅HSO₄，而N₂H₅HSO₄尚未分離得到固體。^[3]N₂H₆SO₄固體在室溫下可以以正交晶系或單斜晶系存在。^[4]

性質

無色無味鱗狀結晶或斜方結晶。微溶於冷水，易溶於熱水，水溶液呈酸性。不溶於醇。在空氣中穩定，不易吸濕。為強還原劑。不可與鹼類、氧化劑共存。有毒，致癌。^[5]^[6]

硫酸肼受熱分解，其分解產物是硫酸銨和硫酸氫銨。^[3]

製備

尿素、次氯酸鈉、液鹼在過錳酸鉀存在下反應，製得肼，經蒸餾，再同硫酸發生中和，生成物經冷卻結晶、過濾、乾燥，製得硫酸肼成品。

{\rm {\ NaOCl+NH_{2}CONH_{2}+2NaOH{\xrightarrow {KMnO_{4}}}N_{2}H_{4}\cdot H_{2}O+}}

{\rm {\ NaCl+Na_{2}CO_{3}}}

{\rm {\ N_{2}H_{4}\cdot H_{2}O+H_{2}SO_{4}\rightarrow N_{2}H_{4}\cdot H_{2}SO_{4}+H_{2}O}}

硫酸氫銨和水合肼反應，也能得到硫酸肼：^[3]

NH₄HSO₄ + N₂H₄·H₂O → N₂H₅HSO₄ + NH₃ + H₂O

用途

用作有機合成試劑，用於製取偶氮二異丁腈，以及製造藥品、殺蟲劑、滅菌劑等。化學鍍時用作還原劑。也用作塑膠和橡膠的發泡劑等。

硫酸肼在美國是營養補充劑，用以對抗癌症造成的患者厭食、消瘦等症狀。^[7]^[8]^[9]^[10] 1970年代中期美國的 Joseph Gold^[11]^[12] 首先提出硫酸肼治療法以控制癌患者惡病質的發展。其原理是癌細胞需要靠葡萄糖的糖酵解來產生能量，而此過程的產物乳酸在肝臟中又經過另一耗能過程——糖異生再轉變為葡萄糖。由於肼是化學性質很活潑的化合物，可能在體內對糖異生中的磷酸烯醇式丙酮酸羧化激酶有抑制作用，因此使用硫酸肼可能阻斷糖異生過程，並因此控制惡病質的發展。^[13] 這一替代醫學療法在1990年代中期因《閣樓》成人雜誌創辦人妻子 Kathy Keeton 的宣傳而廣為人知。Keeton 曾用這一方法治療自己的轉移性乳腺癌，^[14] 並聲稱自己因使用這一療法而使壽命延長數年。不過至今，硫酸肼療法的效果仍然受到很大的爭議。
