Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
vapour pressure: 3.98E-10 mm Hg (5.31E-10 Pa)
Executive summary:

The vapour pressure of Magnesium perchlorate was predicted with MPBPWIN (EPIWIN v4.1) implemented in OECD QSAR Toolbox v4.3.1: 3.98E-10 mm Hg (=5.31E-10 Pa).

Description of key information

3.98E-10 mm Hg (= 5.31E-10 Pa) (MPBPWIN (EPIWIN v4.1) implemented in OECD QSAR Toolbox v4.3.1)

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The study does not need to be conducted as Magnesium perchlorate decomposes at temperatures > 250 °C. Therefore, a limit value based on a recognised calculation method is sufficient.

The vapour pressure of Magnesium perchlorate was predicted with MPBPWIN (EPIWIN v4.1) implemented in OECD QSAR Toolbox v4.3.1 and was calculated to be 3.98E-10 mm Hg (=5.31E-10 Pa).
