Description

Tetraammonium [(Heptylimino)Bis(Methylene)]Bisphosphonate is a high-performance organophosphorus compound, specifically a tetraammonium salt of a heptyl-substituted bisphosphonic acid. This chemical is valued for its superior chelating and scale inhibition properties, making it a critical component in formulations requiring effective metal ion control and dispersion. It is primarily utilized by industries such as water treatment, industrial cleaning, and oilfield chemicals, where it prevents scale formation and stabilizes process fluids under demanding conditions.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling fluids, completion brines, and squeeze treatments to control scale deposition (e.g., calcium carbonate, barium sulfate) in downhole equipment.
• Industrial Cleaning & Detergency: Serves as a key builder and chelant in heavy-duty industrial and institutional cleaning formulations to sequester hardness ions.
• Pulp & Paper Processing: Functions as a dispersant and chelating agent to control metal ions that can interfere with bleaching processes and paper quality.
• Textile Processing: Employed as a stabilizer and sequestrant in dyeing and bleaching baths to improve color fastness and process consistency.
• Personal Care & Cosmetics: Can be used as a stabilizing agent in formulations to enhance the shelf-life and efficacy of active ingredients.

Quality Control

Our production of Tetraammonium [(Heptylimino)Bis(Methylene)]Bisphosphonate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure consistency and performance. Certificates of Analysis (COA) documenting purity, active content, and key physical-chemical parameters are available upon request to support your quality assurance and regulatory 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product quality.
