Manganese bis(phosphinate)

Endpoint summary

Description of key information

Appearance:

Based on available data from various reliable handbooks, the chemical manganese(2+) bis(phosphinate) was observed to be an inorganic odourless, pink coloured granular or crystalline powder in appearance.

Melting point:

Based on available data from reliable handbook, the melting point of chemical manganese(2+) bis(phosphinate) was determined to be greater than 250 degree C.

Boiling point:

Based on available data from reliable handbook,the boiling point of chemical manganese(2+) bis(phosphinate) was determined to be greater than 1500 degree C at 760 mm Hg.

Density:

Based on available data from reliable handbook,the density of chemical manganese(2+) bis(phosphinate) was determined to be 1.2 g/cm3 at 25 degree C.

Particle size distribution (Granulometry):

The particle size distribution of manganese(2+) bis(phosphinate) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 147 micron to 52 micron.

Vapour pressure:

The estimated vapour pressure of the test substance manganese(2+) bis(phosphinate) at 25 deg C was 0.0000028 Pa.

Partition Coefficient:

The study need not be conducted since the chemical is inorganic in nature. Manganese(2+) bis(phosphinate) was observed to be an inorganic odourless,pink coloured crsytals or powder in appearance. Hence, this endpoint was considered for waiver.

Water solubility:

The water solubility of manganese(2+) bis(phosphinate) is determined to be 150000 mg/L at 20°C.

Surface tension:

In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. The manganese(2+) bis(phosphinate) is used as a laboratory chemical, Synthesis of substances, etc. For this use, surface activity is not an important property. Hence this study was considered for waiver.

Flash point:

The study does not need to be conducted because the manganese(2+) bis(phosphinate) is an inorganic compound. Hence this study is considered to be waiver.

Autoflammability:

Manganese(2+) bis(phosphinate)did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that manganese(2+) bis(phosphinate) is not auto-flammable.

Flammability:

Manganese(2+) bis(phosphinate) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Manganese(2+) bis(phosphinate) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Manganese(2+) bis(phosphinate) was considered non-flammable for chemical safety assessment.

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Oxidising properties:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Viscosity:

This end point was considered for waiver since viscosity is an inherent property of a liquid that offers resistance to its flow and manganese(2+) bis(phosphinate) is a solid substance and hence this testing was considered scientifically unjustified for manganese(2+) bis(phosphinate).
