Description

Tripotassium Hydrogen Ethylenediaminetetraacetate is a high-purity, water-soluble chelating agent and a key salt form of EDTA. This compound is critical for applications requiring precise metal ion sequestration in aqueous systems while maintaining a stable pH profile. It is essential for manufacturers in the pharmaceutical, analytical chemistry, and industrial cleaning sectors who demand reliable, high-quality chelants for formulation stability and process control.

Application

• Pharmaceutical Formulations: Used as a stabilizing agent in injectables, ophthalmics, and topical products to chelate trace metal impurities that can catalyze degradation.
• Analytical Chemistry & Laboratory Reagents: Serves as a primary standard and complexometric titrant for the determination of various metal ions.
• Industrial Cleaning & Descaling: A key component in formulations for boiler and cooling system cleaners to control scale from calcium and magnesium.
• Cosmetics & Personal Care: Functions as a chelator in shampoos, lotions, and creams to enhance shelf life and product clarity.
• Food Processing (where compliant): Employed as a sequestrant to preserve color and flavor stability in certain processed foods and beverages.
• Agriculture & Micronutrient Formulations: Used in fertilizer and agrochemical solutions to keep micronutrients bioavailable and prevent precipitation.
• Photography & Imaging: Acts in developer and fixer solutions to control water hardness and improve solution performance.
• Textile & Pulp/Paper Processing: Applied in dyeing processes and pulp bleaching to mitigate interference from metal ions.

Quality Control

Our Tripotassium Hydrogen EDTA is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and analytical applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, purity, and specific tests is provided with every shipment to guarantee traceability and compliance with your specifications.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and reduced performance.
