Magnesium phosphate

Magnesium phosphate (CAS 10043-83-1), also known as newberyite in its mineral form, is an inorganic salt used across food, pharmaceutical, and agricultural industries as a pH buffer and stabilizer. It regulates acidity in formulations and provides a bioavailable source of both magnesium and phosphate in nutritional applications. In food manufacturing, it functions as a buffering agent and anti-caking additive.

This compound is frequently utilized in dry blends, baked goods, and dietary supplements. Pharmaceutical formulators use it as an excipient in tablet and capsule production, where controlled pH and mineral content are critical. In agriculture and animal feed, it supplies essential magnesium and phosphorus to correct soil deficiencies and support livestock nutrition. Water treatment operations apply it to adjust pH and inhibit scale formation.

Magnesium phosphate is supplied as a white powder or granules depending on the intended application. Food-grade and USP/BP grades are available for nutritional and pharmaceutical use. Technical-grade material serves industrial and agricultural markets. Packaging options typically range from small bags to bulk quantities to accommodate both formulation-scale and large-volume procurement needs.
