Description

Magnesium Hydrogen Orthophosphate is an inorganic salt of magnesium and phosphoric acid, commonly known as magnesium phosphate dibasic. This compound serves as a vital source of bioavailable magnesium and phosphate ions, making it a key functional ingredient in numerous industrial and nutritional applications. It is essential for manufacturers in the food, pharmaceutical, and nutraceutical sectors seeking a high-purity mineral fortifier and processing aid.

Application

• Food & Beverage Fortification: Used as a nutritional supplement to enrich products like breakfast cereals, meal replacement shakes, and sports drinks with essential magnesium and phosphorus.
• Pharmaceutical Excipient & Active: Functions as a tablet disintegrant, binder, and a direct source of magnesium in antacid formulations and mineral supplement tablets.
• Nutraceutical & Dietary Supplements: A primary ingredient in magnesium and bone health supplement capsules and powders due to its good bioavailability.
• Animal Feed Premix: Incorporated into feed for livestock, poultry, and aquaculture to support skeletal development, metabolic functions, and overall animal health.
• Technical & Industrial Applications: Employed in ceramics, as a fire retardant additive in certain materials, and in water treatment processes.

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 sealed to prevent absorption of atmospheric moisture, which can lead to caking.
