Description

Dipotassium Dihydrogen [[(2-Ethylhexyl)Imino]Bis(Methylene)]Bisphosphonate is a high-purity, organophosphorus compound that serves as a highly effective chelating agent and scale inhibitor. Its primary value lies in its exceptional ability to sequester di- and trivalent metal ions, preventing scale formation and corrosion in complex aqueous systems. This makes it a critical additive for industrial water treatment, oilfield production, and detergent formulations where performance under demanding conditions is required.

Application

• Industrial Water Treatment: Key component in cooling water and boiler water treatment programs for scale and corrosion inhibition, particularly against calcium, magnesium, and iron scales.
• Oilfield Chemicals: Used in squeeze treatments and as an additive in drilling and completion fluids to control scale deposition in downhole equipment and pipelines.
• Detergent & Cleaning Formulations: Acts as a builder and chelant in industrial and institutional cleaning products to enhance cleaning efficiency by inactivating water hardness ions.
• Pulp & Paper Processing: Employed as a chelating agent in bleaching processes to stabilize peroxides and improve brightness by controlling transition metal ions.
• Textile Processing: Utilized in dyeing and bleaching baths to sequester metal ions that can cause shade variation or fabric degradation.
• Personal Care Products: Incorporated as a stabilizer and chelant in certain cosmetic and personal care formulations.

Quality Control

Our production of Dipotassium Dihydrogen [[(2-Ethylhexyl)Imino]Bis(Methylene)]Bisphosphonate adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by titration, identification by FT-IR, and quantification of key impurities, to ensure consistency and performance. Certificates of Analysis (COA) documenting purity, physical properties, and compliance with agreed specifications are available upon request and accompany every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
