CAS Number: 35218-75-8
5,10,15,20-Tetrakis-(4-Sulfonatophenyl)-21,23H-Porphine (TSPP) is a water-soluble free-base porphyrin widely used as a photosensitizer, biosensor component, and research reagent in insect toxicology and insecticide mechanism studies. Its water solubility and strong light absorption make it applicable in aqueous biological systems for studying ROS generation and oxidative insecticide mechanisms. TSPP also serves as a ligand in the preparation of water-soluble metalloporphyrins used in insecticide enzyme model studies. AB Enterprises supplies TSPP to research laboratories and diagnostic chemical companies. Its broad utility across sensing, photodynamic, and catalytic applications makes it a versatile research compound.
