Used as a photosensitizer in photodynamic therapy for cancer treatment due to its ability to generate reactive oxygen species under light irradiation. Its carboxyphenyl groups allow for easy conjugation to nanoparticles, polymers, or biomolecules, enhancing targeted delivery. Also employed in catalysis, particularly in oxidation reactions, where the iron center acts as an active site. Shows potential in biosensing and imaging applications because of its strong absorbance and fluorescence properties. Stable under physiological conditions, making it suitable for biomedical and diagnostic platforms.
