Description

Dihydrogen Magnesium Ethylenediaminetetraacetate is a high-purity, water-soluble chelating agent specifically formulated as the magnesium salt of EDTA. This compound is valued for its exceptional ability to sequester di- and trivalent metal ions, preventing unwanted precipitation and catalytic activity in sensitive formulations. It serves as a critical additive in pharmaceutical, nutraceutical, and high-end industrial applications where precise metal ion control is paramount for stability and efficacy.

Application

• Pharmaceutical Stabilizer: Used in injectable and ophthalmic solutions to chelate trace metals that can catalyze degradation, thereby extending shelf-life.
• Nutraceutical & Dietary Supplement: Acts as a source of bioavailable magnesium and a stabilizer in liquid vitamin and mineral formulations.
• Cosmetic & Personal Care: Employed in creams, lotions, and serums to improve formulation stability by inactivating metal impurities.
• Industrial Process Chemistry: Serves as a masking agent in chemical synthesis and catalysis to control reaction specificity.
• Laboratory Reagent: Used in analytical chemistry and molecular biology buffers (e.g., TE buffer) for magnesium-dependent enzyme studies.
• Agrochemical Formulations: Enhances the stability and compatibility of micronutrient blends and pesticide solutions.

Quality Control

We supply Dihydrogen Magnesium EDTA in various grades, including Pharmaceutical and Technical, each manufactured under a strict quality management system. Every batch is tested to ensure compliance with relevant specifications for identity, purity, and metal content. A comprehensive Certificate of Analysis (COA) documenting assay, heavy metals, loss on drying, and other critical parameters is provided with each shipment.

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 material is hygroscopic (moisture-sensitive) and must be kept in original packaging until use to prevent caking and degradation due to moisture absorption.
