Description

Ethylenediamine-N,N,N',N'-Tetraaceticaciddisodium-Zincsalt CAS NO 15304-64-0 is a stable, water-soluble zinc chelate of EDTA, widely recognized for its superior sequestering power. This compound is essential for applications requiring precise control of zinc ions in aqueous systems, preventing unwanted precipitation and catalyzed degradation. It is a critical raw material for formulators and manufacturers in the agriculture, personal care, and industrial cleaning sectors who require a reliable and bioavailable source of zinc.

Application

• Agricultural Micronutrient Fertilizers: As a highly effective and stable source of zinc in chelated liquid and foliar fertilizers to correct zinc deficiencies in crops.
• Personal Care & Cosmetics: Used as a stabilizing agent and source of zinc in formulations like shampoos, creams, and lotions to enhance product shelf-life and provide skin benefits.
• Industrial Cleaning & Descaling: Acts as a powerful sequestrant in alkaline and acidic cleaning formulations to control water hardness and inhibit scale formation.
• Chemical Synthesis & Catalysis: Serves as a precursor or catalyst component in organic synthesis and polymerization processes.
• Water Treatment: Employed to control metal ion concentrations and inhibit scaling in industrial water circuits and boiler systems.
• Laboratory & Analytical Reagent: Used in analytical chemistry as a standard and complexometric titrant for the determination of various metal ions.

Quality Control

Our Ethylenediamine-N,N,N',N'-Tetraaceticaciddisodium-Zincsalt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, zinc content, and chelation efficiency. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

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); ensure the container is securely sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking.
