Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
20 November - 01 December 2017
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. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to

OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
1995
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Version / remarks:
2008
Deviations:
no
Principles of method if other than guideline:
Not applicable
GLP compliance:
yes (incl. certificate)
Remarks:
Inspected on 4,5 and 6 July 2016/ Signed on 10 January 2017
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
< -20 °C
Atm. press.:
ca. 1 017 hPa
Decomposition:
no

Results of trials 1 and 2 were not used as the peak was not exploitable.

No melting point was detected for trials 3 and 4 until -20°C. The melting point was stated as : <-20°C.

The crucible was visually checked after the determination: By opening the crucible, no sign of decomposition was observed.

Conclusions:
The melting point of test item was stated as: <-20°C (253.15 K).
Executive summary:

The study was performed in order to determine the melting point of test item according to OECD 102, resp. EU A.1 guideline, using the DSC method.

The melting point of test item is stated as: <-20°C (253.15 K).

Description of key information

The melting point was stated as: <-20°C (253.15K)

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/ EU A1 guideline is available.

It is considered as a key study, and the result is retained as key data.
