Description

Magnesium Dihydrogen Orthophosphate is an inorganic salt of magnesium and phosphoric acid, serving as a vital source of both magnesium and bioavailable phosphate. This compound is essential for applications requiring controlled nutrient release and buffering capacity. It is primarily utilized by manufacturers in the food, pharmaceutical, and agricultural industries for fortification, excipient formulation, and specialty fertilizer production.

Application

• Food & Beverage Fortification: Used as a nutritional supplement and pH regulator in food products and beverages to enhance magnesium and phosphorus content.
• Pharmaceutical Excipient: Acts as a source of magnesium and phosphate in tablet and capsule formulations, including nutritional supplements.
• Specialty Fertilizers: A key component in water-soluble and controlled-release fertilizers, providing essential nutrients for plant growth.
• Animal Feed Additive: Incorporated into premixes to support bone development and metabolic functions in livestock and poultry.
• Laboratory Reagent: Employed in analytical chemistry and research as a buffer agent or a standard in various testing procedures.
• Dental & Oral Care: Used in certain toothpaste and mouthwash formulations for its mineralizing properties.

Quality Control

Our Magnesium Dihydrogen Orthophosphate is produced under a stringent quality management system. We offer grades suitable for food, feed, and technical applications, with specifications aligned to industry standards such as FCC and USP where applicable. Certificates of Analysis (COA) documenting purity, heavy metal content, and other critical parameters are available for every batch upon request, ensuring full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
