Request SDS →DTPMP pentasodium salt (CAS 68155-78-2) is the sodium salt of diethylenetriaminepenta(methylenephosphonic acid), an organophosphonate chelating and scale-inhibiting agent. It functions as a chelating agent, scale inhibitor, and oxidant (bleach) stabilizer in water-treatment and cleaning formulations.
Frequently Asked Questions
What is DTPMP.Na5 used for?
DTPMP pentasodium salt (DTPMP.Na5, CAS 68155-78-2) is an organophosphonate chelating and scale-inhibiting agent. It functions as a chelating agent, scale inhibitor, oxidant/peroxide-bleach stabilizer, and detergent builder/sequestrant in water-treatment and cleaning formulations. RawSource supplies it in bulk to water-treatment and detergent manufacturers.
What is the difference between DTPMP.Na5 and the free acid DTPMPA?
DTPMP.Na5 (CAS 68155-78-2) is the pentasodium salt with a near-neutral pH, while DTPMPA (CAS 15827-60-8) is the free acid form. The sodium salt is chosen for formulations that need reduced acidity; both perform identical chelation and scale-inhibition chemistry. Selection comes down to pH compatibility in your system.
How does DTPMP.Na5 work as a chelating agent?
The molecule's multiple phosphonate groups sequester metal ions such as calcium, magnesium, and iron, holding them in solution to prevent scale deposition and to stabilize peroxide and oxidant systems against metal-catalyzed decomposition. This makes it both a builder and a stabilizer in cleaning and bleaching formulations.
What is the CAS number and formula for DTPMP.Na5?
DTPMP pentasodium salt's CAS number is 68155-78-2 and formula C9H21N3Na7O15P5, classified under HS 2931.49. RawSource provides a Certificate of Analysis and SDS with each bulk shipment to confirm active content.
What is the cost of bulk DTPMP.Na5?
Bulk DTPMP.Na5 pricing depends on volume, active-content specification, packaging, and freight. RawSource quotes against current supply; request a bulk quote with your volume and ship-to for firm pricing.
