Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -30 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: The test item did not freeze during the test. Therefore, no exact freezing temperature can be reported.
- Conclusions:
- The freezing point of the test item was determined to be below -30 °C (253 K).
- Executive summary:
An experimental study was conducted according to OECD Test Guidelines 102 to determine the freezing point of the test item. The test was performed using a sample flask with a screw lid to support a thermometer. For agitating a magnetic bar stirrer was placed into the sample flask. The sample flask is cooled down in a dry ice / acetone bath to -30 °C for a period of 1 h. The test was performed in duplicate. The test item did not freeze during the test. Therefore, no exact freezing temperature can be reported. The freezing point of the test item was determined to be below -30 °C (253 K).
