中文名称:   4-羟基香豆素
 
英文名称:    4-hydroxy-2h-1-benzopyran-2-on
                     4-hydroxycoumarin
                     4-Hydroxy-2H-1-benzopyran-2-one
                     Benzotertonic acid
                     4-hydroxy coumarin
 
性状描述:    微黄色针状结晶。熔点206℃。易溶于乙醇、乙醚和热水。与三氯化铁作用呈棕色。
 
用途:    医药,农药的中间体。用于生产双香豆素、新抗凝,华法林等抗凝血药物。这类4-羟基香豆素衍生物是一类口服抗凝血药物。双香豆素因吸收不规则、不完全,已被华法林等所取代。双香豆素作用维持时间最长(4-7d),华法林较长(3-5d),新抗凝较短(2-4d),香豆素乙酯最短(2-3d)。

          4-羟基香豆素也是一些杀鼠药的中间体,例如杀鼠灵、氯杀鼠灵、克杀鼠、杀鼠萘、联苯杀鼠萘等。杀鼠灵是第一代抗凝血型杀鼠剂,在全世界广泛使用,杀鼠效果很好。

         第二代抗凝血型杀鼠剂是溴联苯杀鼠萘,只要一次投饵即可使鼠中毒致死,在美国杀鼠剂市场中已占30%。

          4-羟基香豆素也是一种香料,香豆素类在植物界分布广泛。牛马吃了腐败的紫苜蓿曾因丧失血凝性而出血致死,这可能是由于植物中香豆精形成双香豆素而造成。
