Additional information

Magnesium hydrogen orthophosphate (CAS 7757-86-0) is an inorganic magnesium and phosphate salt that does not undergo biodegradation. In release to water magnesium hydrogen orthophosphate dissociates to magnesium ions and phosphate species, mostly hydrogen phosphate and dihydrogen phosphate under environmental conditions. The magnesium cation and the hydrogen phosphate anion have no potential mechanism for further hydrolysis. Photodegradation is not relevant for the substance.
