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:
- other: The study was carried out in a laboratory accredited under GLP, however the study itself was not subject to GLP audit. The study followed OECD TG 102 (1995) and Method A1 in Regulation (EC) No 440/2008 without deviations.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Type of method:
- other: differential scanning calorimetry (DSC)
- Melting / freezing pt.:
- 164.3 °C
- Atm. press.:
- >= 100.9 - <= 101.4 kPa
- Remarks on result:
- other: Relative standard deviations: 0.13% (°C) from the four determinations performed.
- Conclusions:
- In a valid, reliable and conclusive study the melting temperature of the test item was determined to be 164.3 °C (437.4 K) at 100.9-101.4 kPa.
- Executive summary:
The study was performed to determine the melting temperature of the test item according to OECD TG 102 (1995) and Method A1 in Regulation (EC) No 440/2008. The mean melting temperature of the test item was determined to be 164.3 °C (437.4 K), with a relative standard deviation of 0.13% (°C) from the four determinations performed. The atmospheric pressure was in the range from 100.9 to 101.4 kPa.
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study was carried out in a laboratory accredited under GLP, however the study itself was not subject to GLP audit. The study followed OECD TG 102 (1995) and Method A1 in Regulation (EC) No 440/2008 without deviations.

- Melting / freezing pt.:
- > 127.4 - < 163.1 °C
- Atm. press.:
- > 99.3 - < 99.8 kPa
- Remarks on result:
- other: Relative standard deviations: 0.79% and 0.33% (°C) from the four determinations performed.
- Conclusions:
- In a valid, reliable and conclusive study the melting temperature of the test item was determined to be 127.4 to 163.1 °C (400.5 to 436.2 K) at 99.3 to 99.8 kPa.
- Executive summary:
To determine the melting temperature of the test item a study was performed according to OECD TG 102 (1995) and Method A1 in Regulation (EC) No 440/2008. The overall melting temperature range of the test item was determined to be 127.4 to 163.1 °C (400.5 to 436.2 K), with relative standard deviations of 0.79% and 0.33% (°C) from the four determinations performed for the start and end temperatures respectively. The atmospheric pressure was in the range 99.3 to 99.8 kPa
