1-Hydroxyethanediphosphonic acid sodium salt (HEDP Na4) is a specialized chemical compound with a unique set of properties that make it valuable across various industrial applications. Understanding these characteristics, including its appearance, molecular formula, and stability, is crucial for effective use and safe handling. At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize educating our clients about the products we supply, ensuring they can maximize benefits while maintaining safety standards.

HEDP Na4 is available in two primary forms: a colorless to yellowish transparent liquid and a white powder. This dual availability offers flexibility for different application requirements and storage conditions. The liquid form is convenient for direct dosing into water systems, while the solid powder is particularly advantageous for use in winter or in regions with freezing temperatures, as it avoids the issues associated with liquid product solidification. The molecular formula for the tetrasodium salt is C2H4Na4O7P2, indicating its phosphonate structure. Its CAS number is 29329-71-3, a key identifier in chemical sourcing and regulatory compliance.

One of the standout properties of HEDP Na4 is its remarkable stability. It is resistant to hydrolysis, meaning it breaks down very slowly in water, and exhibits superior tolerance to chlorine oxidation compared to many other phosphonic acids. This chemical resilience ensures its efficacy over extended periods and in challenging environments. Furthermore, HEDP Na4 forms stable chelating complexes with metal ions such as iron, copper, and zinc, a property that underpins its effectiveness as a scale and corrosion inhibitor. It can even operate effectively at temperatures up to 250°C, showcasing its robust performance profile.

When handling HEDP Na4, particularly the powder form which can be hygroscopic, it is advisable to store it in a cool, dry, and well-closed container, protected from moisture and direct sunlight. Proper personal protective equipment, such as gloves and eye protection, should be used to avoid contact, especially with the concentrated forms. For industries looking to buy HEDP Na4, ensuring the supplier provides comprehensive safety data sheets (SDS) is essential for safe and compliant usage.
