zinc dihydrogen phosphate is an organic compound with the formula O8P2Zn, and the CAS registry number 13598-37-3. Also known as monobasic zinc phosphate, it is used as an anti-corrosion treatment chemical for ferrous metals in electroplating industry. It is a white three-slanting crystal with low melting point and can be found in powder form.

Its natural forms are the minerals hopeite and parahopeite. It can be obtained from oxidation zones of the sphalerite zinc mineral deposit and from secondary deposits formed by the decomposition of pyrite or iron sulfide. It is soluble in water and acetone. Its solution has a very high viscosity and is a good lubricant.

In dentistry, it is an effective luting material for permanent metal and zirconium restorations. However, it does not adhere to enamel, dentin or ceramic and therefore adds no incremental strength to the final restoration. It is also irritating to vital tooth structures due to its application acidity (pH 2.0) and long term acidity once set (pH 4.5-5.0).

The phosphate is generally safe in patients. It ought to be utilized with clinical oversight furthermore subsequent to screening cautiously for cardiovascular, hepatic, and renal infection. It ought not to be utilized with medications that worsen electrolyte unsettling influences, such as diuretics.

It is found in various processed foods as a thickening agent and emulsifier, which additionally controls the pH of the food product. It is an important raw material in the manufacture of phosphate coatings for metal forming operations. It is a key ingredient in the manufacturing of calcium sulfate and magnesium sulfate, which are used as dietary supplements. Recently a 39-year-old patient created tertiary hyperparathyroidism because of chronic oral phosphate supplementation.
