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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- May - Aug 2015
- Reliability:
- 1 (reliable without restriction)

- Type of method:
- other: NA
- Key result
- Melting / freezing pt.:
- >= 116 - <= 117 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- Melting point 116 - 117 °C
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- October 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Samples of the test item and of a reference material (empty crucible) are subjected to the same controlled temperature programme. When the test substance undergoes a phase transition or decomposition the corresponding change of enthalpy gives an endothermic (melting) or exothermic (caused by freezing or decomposition) departure from the base line of the temperature record.
- GLP compliance:
- yes
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- thermal analysis
- Remarks:
- Differential Scanning Calorimetry
- Key result
- Melting / freezing pt.:
- 94.89 °C
- Atm. press.:

- Decomposition:
- yes
- Decomp. temp.:
- 245.2 °C
- Conclusions:
- Melting point 94.89 °C
Decomposition 245.2 °C

Additional information
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.
