Used primarily in the synthesis of organic compounds, it serves as a key intermediate in the production of pharmaceuticals, particularly in the development of anticoagulant drugs like warfarin. Its structure is also utilized in the creation of fragrances and flavoring agents due to its aromatic properties. In addition, it finds application in the field of organic electronics, where it contributes to the development of materials for light-emitting diodes (LEDs) and other optoelectronic devices. Coumarin derivatives show potential in anti-inflammatory and antimicrobial applications, and it is studied for use in UV-resistant polymers and agrochemicals. Its versatility makes it valuable in various industrial and research settings.
