Used as a catalyst in oxidation reactions, particularly in the activation of molecular oxygen and peroxides for selective organic transformations. Exhibits activity in the degradation of pollutants through advanced oxidation processes, making it relevant in environmental remediation. Applied in biomimetic studies due to structural similarity to heme enzymes, supporting research on cytochrome P450 and peroxidase functions. Also investigated in photodynamic therapy and sensing applications owing to its stable porphyrin framework and redox-active metal center.
