Used as an intermediate in organic synthesis, particularly in the development of fluorescent dyes and photoactive compounds. Its bromine functionality allows for coupling reactions, making it valuable in the preparation of xanthone derivatives with potential applications in materials science and pharmaceuticals. Commonly employed in the synthesis of sensors and probes due to the inherent fluorescence properties of the xanthenone core. Also serves as a building block in the creation of complex heterocyclic systems for research in medicinal chemistry.
