Description

Magnesium Galactarate is a magnesium salt of galactaric acid (mucic acid), offering a bio-based source of magnesium with unique chelating and stabilizing properties. This compound is valued for its role as a functional mineral supplement and a versatile chemical intermediate in high-purity applications. It serves critical needs in the pharmaceutical, nutraceutical, and specialty chemical industries, where consistent quality and reliable supply are paramount.

Application

• Pharmaceutical Excipient: Used as a tablet disintegrant, binder, or flow aid in solid dosage formulations.
• Nutraceutical & Dietary Supplements: Serves as a source of bioavailable magnesium in mineral supplement capsules and powders.
• Chelating Agent: Functions as a mild, biodegradable chelator in specialty chemical formulations and cosmetic products.
• Chemical Synthesis: Acts as a precursor or catalyst in organic synthesis and the production of other galactarate derivatives.
• Food Additive (Potential): May be utilized as a firming agent, stabilizer, or pH buffer in specific food applications, subject to regulatory approval.
• Laboratory Reagent: Employed as a standard or reagent in analytical chemistry and biochemical research.
