Melting point / freezing point
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:
- 29 to 29 March 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. Test substance is adequately characterised. Therefore, full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:

Date of manufacture: 08.01.2019
Expration date of the batch: 08.01.2021
UVCB substance;
Purity test date: 18.01.2019 - Key result
- Melting / freezing pt.:
- <= -20 °C
- Atm. press.:
- 1 013.3 hPa
- Decomposition:
- no
- Decomp. temp.:
- 115 °C
- Sublimation:
- no
- Conclusions:
- No melting point exists above -20 "c.
- Executive summary:
The melting point of the test substance was determined under GLP according to OECD 102 / EU A1 guideline,using differential scanning calorimetry. No melting point was measured by DSC above -80 °C. However, since melting may be hindered at low temperatures due to supercooling it should only be assumed that no melting point exists above -20 °C.

Description of key information
No melting point exists above -20 ºC at 101 325 Pa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
A fully reliable experimental study, conducted according to OECD 102/EC A.1 method, is available. Therefore, it is considered as a key study. Differential scanning calorimetry (DSC) is used for determination (equipment: DSC: Mettler-Toledo). The test item and the reference are cooled down to -80 ºC at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. No endothermal effect below ambient temperature is recorded. No melting point is measured by DSC above -80 ºC. However, since melting may be hindered at low temperatures due to supercooling it should only be assumed that no melting point exists above -20 ºC.
