Used in organic synthesis as an intermediate for pharmaceuticals and fluorescent dyes. Commonly employed in the preparation of anticoagulant drugs and coumarin-based derivatives with biological activity. Also utilized in the development of UV-absorbing materials and as a building block in the synthesis of fragrances and flavoring agents due to its pleasant aroma. Plays a role in the fabrication of organic semiconductors and luminescent sensors because of its inherent fluorescence properties.
