Description of key information
Additional information
Purity
Typically the purity of manganese bis(dihydrogen phosphate) is 99.5%.
All impurities present at >1% are other inorganic phosphates or other related inorganic substances, similar to the registered substance, and which do not significantly affect its toxicological and ecotoxicological properties. Phosphoric acid may be present at ≤ 1%.
Physico-chemical properties
Manganese bis(dihydrogen phosphate) has a melting point of >450°C.
The ion chromatography method applied directly quantified the dissolved phosphate content of each sample solution and these have been corrected to equivalent test material concentrations based on the theoretical phosphate content of the test material.
The water solubility of the test material has been determined to be 630 g/l of solution at 20.0 ± 0.5°C in un-buffered glass double-distilled water, resulting in sample solution pH’s of approximately 1.7 to 2.1.
The temperature range of 10°C to 30°C was shown not to have a significant influence on the water solubility of the test material (range 530 to 536 g/l at a nominal loading rate of 50 % w/w).
The solubility of the test material over the environmentally relevant pH range of 4 to 9 gave solubility results and final solution pH’s similar to those obtained using unbuffered water. Thus, it can be anticipated that the water solubility of the test material over the pH range 4 to 9 would be constant, essentially due to the low buffering activities seen in the environment.
Manganese bis(dihydrogen phosphate) is not considered to possess any of the following hazardous physico-chemical properties: autoflammability and/or self-ignition, flammability, explosiveness and oxidising properties.
