其他信息

  • 上游原料:氢氧化铵 --> 五氯化磷 --> 邻氨基苯甲酸 --> 喹唑啉 --> 四口烧瓶 --> 4-羟基喹唑啉
  • Sigma Aldrich:5190-68-1(sigmaaldrich)
  • 下游产品:
  • MOL 文件:5190-68-1.mol
  • 方法一:其制备方法是在四口烧瓶中加入4-(3H)喹唑啉、五氯化磷和三氯氧磷，加热回流2h，反应毕，减压蒸去POCl 3 ，固体残渣用氯仿溶解，倾入冰水混合物中，同时搅拌下滴加36％氨水，使混合液的pH值保持在6～8，分出有机层，干燥，脱溶剂得产品。
  • 用途一:4-氯喹唑啉是杀螨剂喹螨醚的中间体。
  • 方法二:将邻氨基苯甲酸与甲酰胺加热环合，生成喹唑酮-4，然后以五氯化磷和三氯氧磷氯化得到该品。
  • 用途二:常咯啉的中间体。
