用途 该品是医药，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。

The purpose of this article is pharmaceutical intermediates, pesticides. For the production of double-coumarin, a new anticoagulant, warfarin, and other anti-clotting drugs. Such 4 - hydroxycoumarin derivatives are a class of oral anti-clotting drugs. Dicoumarin due to absorption of irregular, incomplete, has been replaced by warfarin. Dual role of maintaining the longest coumarin (4-7d), warfarin longer (3-5d), a new anticoagulant is shorter (2-4d), coumarin, ethyl shortest (2-3d). 4 - hydroxycoumarin rodenticides are also some of the intermediates, such as warfarin, chlorine warfarin, gram kill rats, kill rats naphthalene, biphenyl warfarin naphthalene. Warfarin is the first generation anticoagulant rodenticides blood, is widely used in the world, warfarin works well. The second-generation anticoagulant rodenticides are polybrominated diphenyl blood warfarin naphthalene, as long as you can make a feeding rat poisoning, rodenticides accounted for 30% of the market in the United States. 4 - hydroxycoumarin is a spice widely distributed in the plant kingdom coumarin. Cattle eating alfalfa corruption but had lost hemagglutination and bleeding to death, which may be due to the formation of a plant coumarin dicoumarol caused.
