Product Application of 4-Hydroxycoumarin CAS#1076-38-6

4-Hydroxycoumarin is an intermediate for medicine or pesticide. It is used to produce anticoagulants such as dicoumarol, new anticoagulant, and warfarin. This type of 4-hydroxycoumarin derivative is a class of oral anticoagulants. Dicoumarol has the longest duration of action (4-7 days) and coumarin ethyl ester has the shortest duration (2-3 days). 4-Hydroxycoumarin is also an intermediate for some rodenticides. 4-Hydroxycoumarin is also a spice. Coumarin is widely distributed in the plant kingdom.
