Test No.	Start temperature	Heating rate	Onset temperature
1	-120 °C	+5 °C/min	-111.4 °C
2	-120 °C	+5 °C/min	-111.3 °C
Mean± S.D.			-111.4 ± 0.1 °C

Executive summary:

The melting point of the test substance was determined under GLP according to EU A.1 guideline, using Differential Scanning Calorimetry.

Two main runs were performed and found consistent, so the mean final temperature was retained.

The melting temperature of test substance has been determined to be -111.4 ± 0.1 °C.

Description of key information

Measured melting point (i.e. transition from solid to liquid) = -111.4°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

-111.4 °C

Additional information

A reliable experimental study, conducted according to a recognized EC method and under GLP, is available. It is considered as a key study, and the result is retained as key data.
