Description

Ethylenebisphosphonic Acid O,o-Diethyl O',O'-Diisopropyl Ester is a high-purity organophosphorus compound, specifically a phosphonic acid ester derivative. This chemical serves as a versatile intermediate and functional additive, valued for its ability to act as a chelating agent, scale inhibitor, and corrosion inhibitor in demanding industrial processes. It is essential for manufacturers and formulators in the water treatment, oilfield chemical, and specialty chemical synthesis sectors seeking reliable performance and supply chain stability.

Application

• Industrial Water Treatment: A key component in formulations for scale and corrosion inhibition in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used as a phosphonate-based additive in drilling fluids and production chemicals to control mineral scale deposition and enhance fluid performance.
• Chemical Synthesis: Acts as a crucial phosphorylating agent or protected intermediate in the synthesis of more complex organophosphorus compounds, including pharmaceuticals and agrochemicals.
• Detergent & Cleaning Formulations: Functions as a builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), improving the efficiency of industrial and institutional cleaning products.
• Pulp & Paper Processing: Employed to control scale formation and metal ion interference during bleaching and papermaking processes.
• Textile Auxiliaries: Used in dyeing and finishing baths to sequester metal ions that can cause discoloration or fabric degradation.

Quality Control

Our production of Ethylenebisphosphonic Acid O,o-Diethyl O',O'-Diisopropyl Ester adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure consistency and meet customer specifications. Certificates of Analysis (COA) documenting all critical quality attributes are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and oxidizing agents. The container must be kept tightly sealed due to the product's sensitivity to moisture (hygroscopic).
