Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- other: handbook
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Handbook data are considered from a trusted source. Data have been taken from many sources, including both compilations and the primary literature - where conflicts were found, the value deemed most reliable was chosen. The reference was peer-reviewed. In addition, the reference sources are indicated although not leading to sufficient information on the material & method used.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Method followed unknown; data from handbook.
- GLP compliance:
- not specified

Description of key information
From the handbook results for the dihydrate and hexahydrate form of the substance, it was concluded that the melting/decomposition temperature of anhydrous magnesium nitrate should be > 100°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 100 °C
