Description

Thiocarbohyrazide is a toxic compound made by the reaction of carbon disulfide with hydrazine (hydrazinolysis). It is used in the silver proteinate specific staining of carbohydrates in electron microscopy. 生产方法: 由水合肼与二硫化碳缩合而得。将水合肼水溶液冷至15℃,缓缓加入二硫化碳,即有白色的二硫代甲酰肼析出。加毕,搅拌半小时,然后升温至80℃,反应物开始分解。加热至93℃时反应猛烈,逸出大量硫代氢气体。继续加热3h,静置过夜,滤出结晶,并用4倍沸水重新结晶,即得成品。 用途: 广泛用于有机合成3-硫-4-氨基-6-叔丁基-1,2,4-三嗪-5-酮,该中间体是高校广谱除草剂嗪草酮的重要生产原料。
