Used as a catalyst in various oxidation reactions, particularly in environmental and industrial processes where selective oxidation is required. It shows high efficiency in the degradation of organic pollutants in wastewater treatment due to its ability to activate molecular oxygen or peroxides. Also employed in electrochemical sensors for detecting gases and small molecules, leveraging its redox-active metal center and stable porphyrin structure. Its pyridyl groups enhance solubility in polar solvents and facilitate coordination in supramolecular assemblies, making it useful in the design of metal-organic frameworks (MOFs) and functional materials for catalysis and sensing.
