其他信息

  • 上游原料:二氯甲烷 --> N,N-二甲基甲酰胺 --> 亚硝酸钠 --> 氢硫酸 --> 2-巯基-5-甲基-1,3,4-噻二唑 --> 氯乙醛 --> 氨基乙腈 --> 肼甲酸乙酯
  • 用途一:用作农药中间体
  • 用途三:医药中间体。
  • MOL 文件:4100-41-8.mol
  • 方法一:其制备方法是以氨基乙腈、乙酸和亚硝酸钠进行重氮化反应得到重氮乙腈，将硫化氢通入重氮乙腈和三乙胺的二氯甲烷溶液而得到产品。重氮乙腈溶液很不稳定，易发生爆炸，要特别注意。 也可用氯乙醛和肼甲酸乙酯反应得到ClCH 2 CN＝NNHCOOC 2 H 5 ，再进一步与氯化亚砜反应，环合得到5-氯-1，2，3-噻二唑，然后在二甲基甲酰胺溶剂中将5-氯-1，2，3-噻二唑与氨气反应而得到产品。
  • 用途二:5-氨基-1，2，3-噻二唑是脱叶剂赛草隆的中间体。
