用途 該品是醫藥,農藥的中間體。用于生產雙香豆素、新抗凝,華法林等抗凝血藥物。這類4-羥基香豆素衍生物是一類口服抗凝血藥物。雙香豆素因吸收不規則、不完全,已被華法林等所取代。雙香豆素作用維持時間最長(4-7d),華法林較長(3-5d),新抗凝較短(2-4d),香豆素乙酯最短(2-3d)。4-羥基香豆素也是一些殺鼠藥的中間體,例如殺鼠靈、氯殺鼠靈、克殺鼠、殺鼠萘、聯苯殺鼠萘等。殺鼠靈是第一代抗凝血型殺鼠劑,在全世界廣泛使用,殺鼠效果很好。第二代抗凝血型殺鼠劑是溴聯苯殺鼠萘,只要一次投餌即可使鼠中毒致死,在美國殺鼠劑市場中已占30%。4-羥基香豆素也是一種香料,香豆素類在植物界分布廣泛。牛馬吃了腐敗的紫苜蓿曾因喪失血凝性而出血致死,這可能是由于植物中香豆精形成雙香豆素而造成。

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 Dicoumarin due to absorption of irregular, in免費信息plete, has been replaced by warfarin.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.
