Frequently Asked Questions
What is HEDP disodium salt used for?
HEDP disodium salt (HEDP.Na2, CAS 7414-83-7) is an organophosphonate sequestrant used as a chelating agent, scale and corrosion inhibitor, and deflocculant in cooling- and boiler-water treatment, detergents, industrial cleaning, and as a chelant in cosmetic formulations. RawSource supplies it in bulk to water-treatment and detergent manufacturers.
Is HEDP disodium salt soluble in water?
Yes, HEDP disodium salt is water-soluble, which supports its use as an aqueous sequestrant and scale inhibitor in water-treatment systems. See the SDS and technical data sheet for concentration and use-level guidance.
What is the formula and CAS of HEDP disodium salt?
It is the disodium salt of 1-hydroxyethylidene-1,1-diphosphonic acid, CAS 7414-83-7, molecular formula C2H6Na2O7P2. The CoA confirms identity and active content for each lot.
What is the difference between HEDP and HEDP disodium salt?
HEDP is the free acid; the disodium salt (HEDP.Na2) is the partially neutralized form, supplied for applications that benefit from a higher solution pH and easier handling. RawSource can quote the form that matches your system; specify acid or salt on the RFQ.
What is the price of HEDP disodium salt in bulk?
Bulk pricing depends on active concentration, packaging, order volume, and freight, so RawSource quotes per order rather than listing a price. Submit an RFQ with your target quantity and ship-to for a current bulk quote with CoA and SDS.
