Used as a photosensitizer in photodynamic therapy for cancer treatment due to its ability to generate reactive oxygen species under light irradiation. It is also employed in biochemical research as a fluorescent probe for detecting biomolecules and monitoring cellular processes. Its strong absorption and emission properties make it suitable for use in imaging and sensing applications. Additionally, it serves as a catalyst in certain oxidation reactions and is studied for its potential in antimicrobial photodynamic inactivation.
