Application
4-hydroxy-coumarin is an intermediate of anticoagulant rodenticide, rodenticide, bromadiron, bromurin, rodenticide, rodenticide, rodenticide, flurodenticide, tiamurin, cordenticide, etc.
The anticoagulant drugs can be made in medicine, such as double coumarin ethyl ester and ketone benzyl coumarin.
Used as an intermediate in pharmaceutical and fragrance industry.
Trans -4- hydroxycinnamic acid is the e- isomer of p-coumaric acid, which is a hydroxyl derivative of cinnamic acid and has antioxidant properties. Coumaric acid is a major component of lignocellulose. Studies have shown that p-coumaric acid may reduce the risk of cancer by reducing the formation of cancer-causing nitrosamines.
