Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23 September - 16 November 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
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
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
- Analytical purity: 94.55 %
- Expiration date: 31 December 2017
- Storage condition: at room temperature
Key result
Melting / freezing pt.:
< -60 °C
Decomposition:
yes
Decomp. temp.:
>= 224 °C

Decomposition was observed to commence at 224°C (mean of 222°C (test 1) and 226°C (test 2)).

Conclusions:
The melting/freezing temperature of the test substance was determined to be < -60°C.

Description of key information

From a GLP study (K1, Foster, 2016) according to the EU method A.1 and OECD guideline 102, the melting/freezing temperature of the test substance was determined to be <-60°C.

Key value for chemical safety assessment
