Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adequacy of study:
key study
Study period:
22 April 2010-17 May 2010
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Based on the molecular structure and composition of the test substance a statement rather than a full study was considered sufficient to cover this endpoint. The statement was written by an expert and under GLP.
according to guideline
OECD Guideline 104 (Vapour Pressure Curve)

EU Method A.4 (Vapour Pressure)
GLP compliance:
yes (incl. QA statement)
Type of method:

Key result
20 °C
Vapour pressure:
< 0 Pa
Remarks on result:
not determinable because of methodological limitations
Estimated value

Magnesium nitrate consists of magnesium and nitrate ions which are both non-volatile. Magnesium nitrate is therefore also not volatile (vapour pressure at 20˚C of <1E-05 Pa). Calculation of the vapour pressure from the structure is not possible.

Magnesium nitrate consists of the non-volatile magnesium and nitrate ions and is therefore not volatile. The vapour pressure of magnesium nitrate is estimated to be < 1E-5 Pa at 20°C.

Description of key information

The inorganic solid substance consists of non volatile magnesium and nitrate ions. The volatilty of this substance is estimated to be < 1  E-5 Pa at 20°C.

Key value for chemical safety assessment

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

Additional information

Calculation of the vapour pressure is not possible for an inorganic substance (not within the applicability domain of the databases).
