Magnesium hydrogen phosphate

Magnesium hydrogen phosphate (CAS 7757-86-0 ), also known as dibasic magnesium phosphate or MDHP, is an inorganic salt used across food, pharmaceutical, and industrial applications as a pH buffer and mineral source.

Its controlled solubility and buffering capacity make it a practical choice for formulators managing pH stability and mineral fortification simultaneously. In pharmaceutical manufacturing, MDHP functions as a tablet excipient and buffering agent.

This material helps to stabilize active ingredients sensitive to pH shifts. Feed and agricultural applications use it as a bioavailable magnesium and phosphorus supplement, supporting mineral balance in livestock nutrition programs.

Water treatment processes employ it to adjust pH and reduce corrosion in distribution systems by maintaining stable carbonate equilibrium. Food manufacturers incorporate it as a mineral additive and acidity regulator.

It is commonly found in fortified products, dietary supplements, and processed foods. Magnesium hydrogen phosphate is available as a white crystalline powder or granules, with trihydrate being the most commercially prevalent form.

Standard grades include food-grade ( FCC ), pharmaceutical-grade ( USP / BP ), and technical-grade material to suit different end-use requirements. Bulk supply is typical for industrial and agricultural buyers.

Smaller packaging is also available for pharmaceutical and food applications. This ensures that the material meets the specific handling and safety requirements of various manufacturing environments and regulatory standards.
