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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Remarks on result:
- not determinable
- Remarks:
- The substance shows endothermic reactions above 65°C. This can be attributed to rearrangements in the crystal structure due to the presence of water, which evaporates at elevated temperatures. Boiling temperature in its classic sense cannot be determined.
- Conclusions:
- The boiling point could not be determined as the test substance showed endothermic reactions above 65°C.
- Executive summary:
To determine the boiling temperature of the test substance a study was performed according to EU Method A.2 in compliance with GLP. A boiling point in the classical sense cannot be determined. The test substance showed endothermic reactions above 65°C. These effects can be attributed to rearrangements in the structure of the crystal due to the presence of crystal water.

Description of key information
The test substance showed endothermic reactions above 65°C. These effects can be attributed to rearrangements in the structure of the crystal due to the presence of crystal water. At elevated temperatures, gaseous water is evaporated. A boiling point in the classical sense cannot be determined.
Key value for chemical safety assessment
Additional information
Data from a GLP-compliant guideline study, adequate for assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
