HEDP 98%
SINOBIO
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid
(HEDP)
CAS No. 2809-21-4
Molecular Formula: C2H8O7P2
Molecular weight: 206.02
Hazard class/UN No./Packaging: UN 3265 8/PG III
Structural Formula:
Properties:
HEDP can react with metal ions in water system to form hexa-element chelating complex, especially with calcium ions.
HEDP has good anti-scale and visible threshold effects. When used in combination with other water treatment chemicals, it shows ideal synergistic effects.
HEDP solid state is a high purity product, suitable for cold winter areas; Because of its high purity, it is especially used as the cleaning agents in electronics industry, and additives in daily chemicals.
Specification:
Item | Standard |
