Description

Disodium 2,2'-[Ethylenebis(Oxy)]Diacetate is a high-purity, water-soluble organic salt widely used as a versatile chelating agent and stabilizer in demanding industrial and pharmaceutical processes. Its molecular structure allows it to effectively sequester metal ions, preventing unwanted precipitation and catalytic degradation, which is critical for product stability and performance. This compound is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking reliable, high-quality raw materials for complex formulations.

Application

• Pharmaceutical Synthesis & Formulation: Acts as a stabilizing agent and metal chelator in injectable and ophthalmic solutions to enhance shelf-life and compatibility.
• Personal Care & Cosmetics: Used in creams, lotions, and serums to improve formulation stability by binding trace metals that can cause rancidity or discoloration.
• Industrial Cleaning & Detergents: Serves as a key builder and chelant in specialty cleaning formulations to control water hardness and boost surfactant efficiency.
• Chemical Synthesis & Catalysis: Employed as a ligand or buffer in organic synthesis and catalytic processes to control reaction conditions and metal ion activity.
• Agrochemicals: Incorporated into certain pesticide and fertilizer formulations to enhance stability and bioavailability of active ingredients.
• Water Treatment: Functions as a scale inhibitor and dispersant in boiler and cooling water systems.

Quality Control

Our Disodium 2,2'-[Ethylenebis(Oxy)]Diacetate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, related substances, and residual solvents are available for every shipment 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
