Discontinued product4-Pyridylmethylphosphonic acid
CAS:4-Pyridylmethylphosphonic acid is an inorganic compound that is a ligand for the metal Ruthenium. It is used in organic synthesis as a photosensitizer and a potentiometric titrant. The ligand binds to the metal through one or more of its oxygen atoms, forming a coordination complex. The bond cleavage reaction occurs when the molecule absorbs light of sufficient energy, causing it to break into two parts. 4-Pyridylmethylphosphonic acid is not very soluble in water and is therefore used as an electrolyte in potentiometric titrations. The pH of the solution will change depending on the concentration of the acid. 4-Pyridylmethylphosphonic acid can also be used as a catalyst for certain organic reactions such as esterification and transesterification reactions.
