Description

Sodium Trihydrogen Ethylenediaminetetraacetate is a versatile chelating agent and a key intermediate in the synthesis of EDTA salts. This compound is crucial for industries requiring precise control over metal ion activity, preventing unwanted precipitation and catalyzed degradation. It is primarily utilized by manufacturers in the chemical, pharmaceutical, and personal care sectors for formulating stabilizers, sequestrants, and analytical reagents.

Application

• As a chelating agent precursor for the synthesis of tetrasodium EDTA and other EDTA salts.
• Stabilizer and sequestrant in industrial cleaning formulations and detergent builders to control water hardness.
• Intermediate in the production of pharmaceutical grade chelating agents for drug formulations and as a component in buffer solutions.
• Used in analytical chemistry as a reagent for complexometric titrations and metal ion analysis.
• Application in cosmetic and personal care products to enhance stability and shelf-life by chelating trace metals.
• Laboratory research chemical for studying metal-ligand interactions and coordination chemistry.
• Potential use in agricultural formulations as a micronutrient carrier and stabilizer.
• Component in water treatment processes to inhibit scale formation caused by calcium and magnesium ions.

Quality Control

Our Sodium Trihydrogen Ethylenediaminetetraacetate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
