Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Study performed in accordance with OECD guideline and well documented.
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
>= 8 - <= 13 °C
Atm. press.:
101.3 kPa

The sample shows an endothermic melting peak in the 5 to 18 °C region.

Just before the exothermic peak there is an exothermic relaxation peak. This indicates that the

sample was trapped in a glassy state on cooling. On raising the temperature crystallisation occurred.

 Measurement  Onset / °C Peak / °C 
 #1  7.4  12.5
 #2  8.6  13.1

The mean onset is selected as giving the best value of the start of melting and the mean peak the end of melting.

The melting point of the test item is 8 - 13 °C.

Melting range (DSC) is 8 - 13 °C.
Executive summary:

The melting point of the test item was determined by DSC according OECD guideline no. 102 to be 8 - 13 °C at 101.3 kPa.

Description of key information

Melting range (DSC): 8 - 13 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
8 °C

Additional information

The melting point of the test item was determined by DSC according OECD guideline no. 102 to be 8 - 13 °C.
