Na-DTPMP (32%) is a water-soluble, high-performance phosphonate chelating and scale-inhibiting agent. It exhibits strong sequestration of divalent metal ions (Ca²⁺, Fe²⁺/Fe³⁺), making it useful in water treatment and industrial cleaning applications. Its multi-functional structure enables both chelation and corrosion inhibition in alkaline conditions.
