Description

Magnesium Bis(Hydrogen Carbonate) is a magnesium salt of carbonic acid, known for its role as a source of bioavailable magnesium and carbon dioxide. This compound is significant for its utility in applications requiring a controlled release of magnesium ions and effervescence. It is primarily needed by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for formulating supplements, antacids, and functional ingredients.

Application

• Pharmaceutical Formulations: Used as an active ingredient or excipient in effervescent tablets and antacid preparations.
• Nutraceutical & Dietary Supplements: Serves as a source of bioavailable magnesium in mineral supplement products.
• Food & Beverage Additive: Functions as an acidity regulator, firming agent, or source of carbonation in specific food-grade applications.
• Chemical Synthesis: Acts as a mild base or a source of magnesium and carbonate ions in organic and inorganic synthesis.
• Water Treatment: Employed in processes for pH adjustment and as a magnesium source in mineral enrichment.
• Laboratory & Research: Used as a reagent in analytical chemistry and life science research.
