Used as a catalyst in oxidation reactions, particularly in the selective oxidation of hydrocarbons. It is effective in mimicking cytochrome P450 enzymes, making it valuable in biomimetic catalysis. Commonly applied in environmental chemistry for the degradation of organic pollutants. Also utilized in electrochemical sensors due to its redox activity and stability under various conditions. Shows potential in photodynamic therapy and as a photosensitizer in light-induced reactions.
