- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 09 July 2018 – 12 July 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- - Batch n°: 2712-106
- Analytical purity: 100%
- Expiration date: not indicated
- Storage condition: at room temperature - Key result
- Melting / freezing pt.:
- >= -12.6 - <= 53.2 °C
- Decomposition:
- no
- Remarks on result:
- other: Multiple endotherms were observed during each test run. This is suspected to be due to the presence of different chain length components.
- Remarks:
- No atmospheric pressure was reported
- Conclusions:
- The melting temperature of the test item was determined to range from -12.6 to 53.5°C.

Description of key information
According to a GLP study performed according to OECD guideline 102 and EU Method A.1, the melting point range of the test substance is -12.6 to 53.2°C (K1, Dekra, 2018).
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
