Description

Tetrasodium [(Butylimino)Bis(Methylene)]Bisphosphonate is a high-performance organophosphonate compound widely used as a scale and corrosion inhibitor in industrial water treatment systems. Its unique molecular structure provides excellent chelating and threshold inhibition properties, making it effective even at low dosages. This chemical is essential for industries requiring reliable protection of equipment from mineral scale deposition and metal corrosion, such as cooling water circuits, boiler systems, and oilfield operations.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor for calcium carbonate, calcium sulfate, and barium sulfate in cooling towers, boilers, and reverse osmosis systems.
• Corrosion Control: Functions as a corrosion inhibitor for ferrous and non-ferrous metals in closed-loop and open recirculating water systems.
• Oilfield Chemistry: Used in squeeze treatments and as an additive in drilling and completion fluids to prevent scale formation in downhole equipment and formations.
• Detergent & Cleaning Formulations: Acts as a builder and chelating agent in industrial and institutional cleaning products to sequester hardness ions.
• Pulp & Paper Processing: Employed to control scale in digesters, washers, and bleach plants, improving operational efficiency.
• Textile Processing: Used in dyeing and finishing baths to prevent scale buildup on machinery and ensure consistent fabric quality.

Quality Control

Our production of Tetrasodium [(Butylimino)Bis(Methylene)]Bisphosphonate adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise specifications for active content, pH, and impurity profiles. Certificates of Analysis (COA) documenting purity, identity, and key physical-chemical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive); ensure the original container is securely sealed after each use to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
