Nitrilotris(methylene)triphosphonic acid (Cat No.:R046816) is an organophosphorus compound with the formula N[CH₂PO₃H₂]₃. It appears as a white crystalline solid and functions as a chelating agent and scale inhibitor. NTMP is widely used in water treatment, detergents, and industrial cleaning agents due to its strong ability to bind metal ions like calcium and magnesium, preventing scale formation. It also finds application in the textile, paper, and oil industries. NTMP offers high chemical stability and resistance to hydrolysis, making it effective under harsh conditions. Its structure features three phosphonic acid groups linked to a central nitrogen atom.
