Molecule Structure Image



Coumarin is a pleasantly fragrant chemical compound found in many plants. It is used in the pharmaceutical industry as a precursor molecule in the synthesis of a number of synthetic anticoagulant pharmaceuticals similar to dicoumarol, notably warfarin and some even more potent rodenticides that work by the same anticoagulant mechanism. It has been used in the treatment of lymphedema and also used as aroma-enhancer in pipe tobaccos and certain alcoholic drinks, although it is generally banned as a flavorant food additive, due to concerns about hepatotoxicity coumarin causes in animal models. It is also used as a gain medium in some dye lasers.
