Description

Dipotassium Dihydrogen (1-Hydroxyethylidene)Bisphosphonate is a highly effective bisphosphonate salt widely utilized as a scale and corrosion inhibitor in industrial water treatment systems. Its primary value lies in its exceptional ability to chelate metal ions, preventing the formation of problematic mineral scales like calcium carbonate and calcium sulfate, even under high-stress conditions. This makes it a critical component for industries requiring reliable water management, such as cooling towers, reverse osmosis systems, and oilfield operations to protect infrastructure and ensure operational efficiency.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling water, boiler water, and desalination (reverse osmosis) systems.
• Oilfield Chemistry: Used in squeeze treatments and as an additive in drilling and completion fluids to control scale formation in downhole equipment and pipelines.
• Detergent & Cleaning Formulations: Acts as a builder and chelating agent to sequester hardness ions (Ca²⁺, Mg²⁺), enhancing the cleaning efficiency of industrial and institutional detergents.
• Pulp & Paper Industry: Employed in process water systems to prevent scale deposition on machinery and improve bleaching efficiency.
• Textile Processing: Used to prevent scale buildup in dyeing and finishing baths, ensuring consistent color quality and fabric handling.
• Metal Surface Treatment: Serves as a component in formulations for metal cleaning, pickling, and plating baths to control undesirable precipitation.

Quality Control

Our production of Dipotassium Dihydrogen (1-Hydroxyethylidene)Bisphosphonate adheres to stringent quality management protocols. Every batch is subjected to comprehensive analytical testing, including assay, impurity profiling, and physical characterization, to ensure it meets precise customer and industry specifications. Certificates of Analysis (COA) documenting purity, pH, and other critical parameters are provided as standard, guaranteeing traceability and consistent performance for your formulations and processes.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking. Keep away from strong acids and strong oxidizing agents.
