Used as a fluorescent probe in biological imaging due to its ability to emit strong green fluorescence under UV or blue light excitation. It is particularly effective in tracking cellular processes and monitoring changes in local polarity within membranes or proteins. Its methoxy and hydroxy groups enhance solubility and binding selectivity, making it suitable for labeling hydrophilic environments in live cells. Also employed in photodynamic therapy research for its photosensitizing properties, where it generates reactive oxygen species upon light exposure, aiding in targeted cell destruction. Additionally, it serves as a building block in synthesizing xanthone-based derivatives with potential antimicrobial and anticancer activities.
