Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:

- Study period:
- 13 December 2011-16 March 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Type of method:
- thermal analysis
- Remarks:
- Differential scanning calorimetry.
- Melting / freezing pt.:
- 15 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- The melting point of the test substance is 15 ± 3 °C.
- Executive summary:
The melting point of the test substance was determined according to the OECD Guideline 102 using differential scanning calorimetry. At 1013 hPa, the melting point is 15 +/- 3 °C.
Reference
The sample shows an endothermic melting peak in the 12 to 25 °C region. The much smaller endothermic peak in the -26 to -11 °C region may be due to melting of minor components or processes occurring in the frozen sample.
Individual values:
Measurement Onset Peak
#1 15.0 °C 20.6 °C
#2 15.2 °C 20.7 °C
The mean onset is selected as giving the best value of the melting point. The difference between the lower onset value and the higher peak value is used to estimate the uncertainty.
Description of key information
The melting point of the test substance is 15 ± 3 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 15 °C
Additional information
The melting point of the test substance was determined according to the OECD Guideline 102 using differential scanning calorimetry. At 1013 hPa, the melting point is 15 +/- 3 °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).
