Used as a catalyst in oxidation reactions, particularly in the degradation of organic pollutants under mild conditions. Exhibits high stability and selectivity in homogeneous catalytic systems. Applied in environmental chemistry for the treatment of wastewater containing aromatic compounds. Also utilized in sensor development for detecting oxygen and reactive oxygen species due to its redox-active metal center. Shows potential in photodynamic therapy research owing to its ability to generate singlet oxygen upon light irradiation. Employed in electrochemical studies as a mediator in modified electrodes for biosensing applications.
