Bis(3-sulfonatophenyl)(3,5-di-trifluoromethylphenyl)phosphine, disodium is a covalent molecule that is cytocompatible and extracellular. It has been shown to have a strong binding affinity for intracellular targets such as the cell membrane. This molecule can be used for tethering of noncovalent molecules to intracellular targets. Bis(3-sulfonatophenyl)(3,5-di-trifluoromethylphenyl)phosphine, disodium interacts with linkers containing palladium catalysts to form covalent bonds with the cell membrane. The bond between the linker and the cell membrane is temporary due to cleavage by the enzyme phospholipase A2 (PLA2).
