Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

A study for the endpoint 'vapour pressure' has not been performed for manganese bis(dihydrogen phosphate). For the purpose of environmental fate modelling, the key value for chemical safety assessment has been set at  0.000001 Pa as recommended by the ECHA Guidance document Appendix R.7.13-2: Environmental risk assessment for metals and metal compounds (July 2008).

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

An adaptation from the standard testing regime is justified on the following basis:

According to Annex VII, section 7.5, column 2 of Regulation No. 1907/2006 (REACH), a study for the vapour pressure need not be conducted if the melting point is above 300°C. As the melting point of manganese bis(dihydrogen phosphate) has been determined to be >450°C, a study for vapour pressure is not scientifically justified.
