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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 947-037-7 | CAS number: -
Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Reliable information from standard operating procedure; measurement according to company guideline
- Principles of method if other than guideline:
- Determination of melting point; measurement according to company guideline.
- Type of method:
- thermal analysis
- Key result
- Melting / freezing pt.:
- 174 °C
- Decomposition:
- no
- Decomp. temp.:
- > 450 °C
- Remarks on result:
- other: Sharp endothermic peak at melting point
Reference
A minor exorthermic process was observed in the 254 - 300°C region. This may lead to a pressure increase in closed systems, if it is due to a partial decomposition of the reaction mass.
The decomposition test shows a small endothermic peak at 357 - 410°C. This most likely corresponds to a non-exothermic composition.
Description of key information
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 174 °C
Additional information
no decomposition up to 450°C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
