Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 / freezing pt.:
67.4 °C
Atm. press.:
1 021.25 hPa

Results and Discussion

The temperature range for the investigation of the melting point was fixed between 40 °C and 140 °C. A sharp endothermic signal was recognizable in the range of 67-70 °C. For two runs the following melting points were resulting:

run 1: 67,46 °C

run 2: 67,27 °C


The evaluation of endothermic signals for both runs results in a middle melting point of the test item of 67.4 °C (onset temperatures).

A melting point value of 67.4 °C (at 1021.25 hPa) was determined for the test according to E.U. Method A.1.

Description of key information

Melting point: 67.4 °C at 1021.25 hPa (EU Method A.1, differential scanning calorimetry)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
67.4 °C
