Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing 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.1 (Melting / Freezing Temperature)
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 1
- GLP compliance:
- yes
- Type of method:
- method to determine freezing temperature
- Melting / freezing pt.:
- 20.8 °C
- Conclusions:
- The freezing point of the test substance is 20.8 °C (294 K).
- Executive summary:
The study was performed to EC Method A.1 and in compliance with GLP. The pure test substance was found to have a freezing point of 20. 8 °C (294 K), i.e. it is normally present as a liquid at room temperature.

RESULTS
- Determination 1: 20.5 °C
- Determination 2 : 21.1 °C
- Mean [3 sig. figs.]: 20.8 °C
- Supercooling was observed with the temperature dropping to about 17 °C prior to solidification at the reported 'plateau' temperature.
Description of key information
20.8 °C, pure test substance, OECD TG 102, method to determine freezing temperature, EU Method A.1, Husband 1997
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 20.8 °C
Additional information
Another study was performed to determine the freezing point of the test substance in technical material in accordance with OECD TG 102 and in compliance with GLP. A freezing point of 17.5 °C was observed.
