Description

Ammonium Trihydrogen [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is a high-purity, organophosphonate compound widely recognized for its exceptional chelating and scale inhibition properties. This specialized chemical is engineered to deliver superior performance in complex aqueous systems where control of metal ions and mineral deposits is critical. It is an essential component for formulators and process engineers in the water treatment, detergent, and textile industries seeking to enhance system efficiency and prevent costly scaling.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems, particularly for controlling calcium carbonate and sulfate scales.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), improving surfactant efficacy and preventing soap scum in laundry and dishwashing products.
• Textile Processing: Used as a peroxide stabilizer and sequestrant in bleaching and dyeing baths to prevent catalytic decomposition of hydrogen peroxide by metal ions, ensuring uniform fabric treatment.
• Pulp & Paper Manufacturing: Employed in bleaching sequences to chelate transition metals, enhancing bleach stability and protecting cellulose fibers from degradation.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments to prevent mineral scale formation in downhole equipment and pipelines, ensuring uninterrupted flow.
• Personal Care Products: Incorporated as a chelating agent in formulations to stabilize products by binding trace metals that can cause rancidity or discoloration.

Quality Control

Our Ammonium Trihydrogen [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, active content, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting identity (IR), assay (Titration), pH, and other critical parameters is provided with every shipment to guarantee consistency and traceability for your quality assurance protocols.

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); the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
