Used in organic synthesis as an intermediate for pharmaceuticals and fluorescent dyes. Serves as a building block in the preparation of anticoagulant drugs and coumarin-based derivatives with biological activity. Commonly employed in the development of photoactive compounds due to its favorable UV absorption and emission properties. Also utilized in the synthesis of fragrances and flavoring agents for its pleasant aromatic character. Plays a role in the fabrication of organic semiconductors and luminescent materials for optoelectronic devices.
