Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Guideline study not under GLP.
Qualifier:
according to guideline
Guideline:
other: No data
GLP compliance:
not specified
Type of method:
other: Differential scanning calorimetry
Melting / freezing pt.:
-43 °C
Atm. press.:
101.325 kPa
Remarks on result:
other: Standard atmospheric pressure is assumed.

A transition involving a change in enthalpy occurs at -43 degrees C. This is assigned to a phase change, likely freezing.

Conclusions:
Under the study conditions,the freezing point of the test substance was determined to be -43 °C at 101.325 kPa.
Executive summary:

A study was conducted to determine the melting point of the test substance, using the differential scanning calorimetry (DSC). Under the study conditions,the freezing point of the test substance was determined to be -43 °C at 101.325 kPa (Sohar, 2012).

Description of key information

The freezing point of the test substance was determined using the differential scanning calorimetry (DSC) (Sohar, 2012).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
