Used as a catalyst in oxidation reactions, particularly in the activation of molecular oxygen and peroxides for selective organic transformations. Exhibits high activity in the oxidation of hydrocarbons, alcohols, and sulfides under mild conditions. Employed in biomimetic studies due to structural similarity to heme enzymes, enabling research on cytochrome P450 mechanisms. Also applied in electrochemical systems for oxygen reduction reactions and in the development of sensors. Shows potential in photodynamic therapy research owing to its ability to generate reactive oxygen species when exposed to light.
