Description

EDTA Dipotassium Magnesium Salt, Dihydrate is a high-purity, water-soluble chelating agent complexed with magnesium. This compound is valued for its ability to effectively sequester di- and trivalent metal ions, thereby stabilizing formulations and enhancing product performance. It is essential for manufacturers in the pharmaceutical, cosmetic, and analytical reagent industries requiring a bioavailable magnesium source with controlled metal ion activity.

Application

• Pharmaceutical Formulations: Used as a source of bioavailable magnesium and a stabilizing agent in injectable solutions, tablets, and nutritional supplements.
• Cosmetic & Personal Care: Acts as a chelating agent in creams, lotions, and shampoos to improve shelf-life by inactivating trace metal ions that catalyze oxidation.
• Analytical Chemistry: Serves as a standard or buffer component in complexometric titrations and as a masking agent in various analytical procedures.
• Food & Beverage (where compliant): Potential use as a sequestrant and stabilizer, subject to local food-grade regulations and specifications.
• Industrial Processes: Employed in water treatment, textile processing, and agrochemical formulations to control metal ion interference.
• Biochemical Research: Utilized in cell culture media and molecular biology buffers to maintain magnesium-dependent enzymatic activity while chelating contaminating heavy metals.

Quality Control

Our EDTA Dipotassium Magnesium Salt, Dihydrate 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 parameters such as assay, purity, and heavy metal content, is provided with every shipment to guarantee traceability and compliance.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect weight and stability.
