Description

Diethyl Bis(2-Hydroxyethyl)Aminomethylphosphonate is a multifunctional organophosphorus compound that serves as a versatile intermediate and additive. Its unique structure, featuring both phosphonate and tertiary amine groups, provides excellent chelating, flame-retardant, and scale-inhibiting properties. This chemical is essential for formulators and manufacturers in sectors requiring high-performance water treatment chemicals, polymer stabilizers, and specialty functional fluids.

Application

• Primary component in advanced water treatment formulations for scale and corrosion inhibition in industrial cooling and boiler systems.
• Key intermediate for synthesizing flame-retardant agents and plasticizers used in polymers, textiles, and coatings.
• Effective chelating agent in metal finishing, electroplating baths, and as a stabilizer in peroxide solutions.
• Used in the formulation of detergents and cleaning agents for its sequestration and anti-redeposition properties.
• Precursor in the production of quaternary ammonium compounds and other specialty surfactants.
• Additive in lubricants and hydraulic fluids to enhance anti-wear and extreme pressure performance.
• Component in oilfield chemicals for scale control in production and injection wells.
• Research and development chemical for novel pharmaceutical and agrochemical active ingredients.

Quality Control

Our Diethyl Bis(2-Hydroxyethyl)Aminomethylphosphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications and consistent performance. Certificates of Analysis (COA) documenting purity and key physical-chemical parameters are available for all commercial shipments upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
