Description

Diammonium Dihydrogen [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is a highly effective organophosphorus compound belonging to the class of amino bisphosphonates. Its primary value lies in its powerful chelating and scale inhibition properties, making it a critical component for managing water quality and preventing mineral deposits in industrial systems. This product is essential for industries requiring robust solutions for corrosion and scale control, such as water treatment, oilfield operations, and industrial cleaning formulations.

Application

• Industrial Water Treatment: Acts as a superior scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Oilfield Chemistry: Used in squeeze treatments and water flooding operations to control scale formation (e.g., calcium carbonate, barium sulfate) in downhole and surface equipment.
• Detergent & Cleaning Formulations: Serves as a builder and chelating agent to sequester hardness ions (Ca²⁺, Mg²⁺) and enhance cleaning efficiency.
• Pulp & Paper Industry: Employed as a chelant in bleaching processes and to control metal ion catalyzed decomposition of bleaching agents.
• Textile Processing: Prevents scale buildup on machinery and acts as a dispersant for dyes and pigments.
• Metal Surface Treatment: Used in pickling and plating baths to control metal ions and improve surface finish quality.

Quality Control

Our Diammonium Dihydrogen [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance, meeting the specifications required for industrial applications. Certificates of Analysis (COA) documenting key parameters such as active content, pH, and impurity levels are available upon request to support 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
