Used in organic synthesis as a fluorescent probe due to its extended conjugated system and ability to emit light upon excitation. Its structure allows for incorporation into more complex molecules for studying biological systems, particularly in imaging cell components with high contrast. Also employed in the development of photodynamic therapy agents, where it helps generate reactive oxygen species under light exposure to target cancer cells. Additionally, serves as a building block in the preparation of novel chromene-based pharmaceuticals and optoelectronic materials owing to its electron-accepting and light-responsive properties.
