Request SDS →Tetrasodium Etidronate (CAS 3794-83-0) is the tetrasodium salt of 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP), an organophosphonic chelating agent. /CIR, it functions as a chelating, anti-scaling, and dispersing agent in cleaning and water-treatment systems.
Frequently Asked Questions
What is the tetrasodium salt of 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP.Na4)?
It is Tetrasodium Etidronate (CAS 3794-83-0), the tetrasodium salt of HEDP, an organophosphonic chelating agent with formula C2H4Na4O7P2. It functions as a chelating, anti-scaling, and dispersing agent.
What is HEDP.Na4 used for?
It is used as a chelating agent to sequester metal ions in cleaning and process water, as a scale inhibitor to control carbonate and sulfate scale, as a dispersant in cleaning formulations, and as a builder/sequestrant in detergents and cleaners.
What is 1-hydroxyethylidene-1,1-diphosphonic acid?
HEDP is an organophosphonic (phosphonate) acid that strongly chelates metal ions and inhibits scale and corrosion. The tetrasodium salt supplied here is the fully neutralized form, used where a less acidic, ready-to-dose chelant is preferred.
What HS code applies to HEDP.Na4?
It ships under HS 2931.90, covering other organo-inorganic compounds. Confirm the destination-country classification with your customs broker.
What packaging and documentation does RawSource supply?
RawSource supplies HEDP.Na4 in bulk packaging such as drums, totes, IBCs, or bags depending on whether the solution or solid grade is ordered, with CoA and SDS available on request. Request a bulk quote with your target grade and volume.
