Coumarin is a classic natural and synthetic fragrance compound with sweet vanilla and hay-like aroma. It is widely used in daily flavoring, cosmetics, perfume and soap essence formulation.

It serves as an important pharmaceutical intermediate for the synthesis of anticoagulant drugs, anti-inflammatory agents and vasodilator related derivatives. It is also applied in agrochemicals as plant growth regulator and pesticide intermediate. In industrial fields, it can be used as brightener, plating additive and analytical reagent for chemical detection.
