Description

Magnesium Dimetaphosphate is an inorganic magnesium salt of dimetaphosphoric acid, valued for its role as a source of bioavailable magnesium and a functional phosphate. This compound is significant in applications requiring controlled mineral release and phosphate chemistry. It is primarily utilized by manufacturers in the nutraceutical, food fortification, and specialty chemical industries.

Application

• Dietary Supplements & Nutraceuticals: Used as a magnesium source in vitamin-mineral complexes and functional foods.
• Food Fortification: Acts as a mineral fortificant in beverages, dairy products, and baked goods to enhance nutritional value.
• Pharmaceutical Excipients: Employed in certain tablet formulations as a binder or disintegrant.
• Technical & Industrial Chemistry: Serves as a precursor or intermediate in the synthesis of other phosphate compounds and ceramic materials.
• Laboratory Research: Used as a reagent in analytical chemistry and materials science research.
