Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
yes
Type of method:
thermal analysis
Remarks:
Differential Scanning Calorimetry
Melting / freezing pt.:
-60 °C
Subl. temp.:
°C
Remarks on result:
other: Glass transition

A reproducible glass transition was found at -60°C in the 2nd heating.

An endothermic peak starting at about 240°C onset shows the vaporization of the test substance.

Exothermic reaction was not observed up to 500°C.

No melting point was found between -100°C and vaporization of the test substance.

The estimated accuracy is +/-1°C.

Conclusions:
No melting point was found between -100°C and the vaporization of the test item.
A reproducible glass transition was found at -60°C.
Executive summary:

In this guideline (OECD 102) study conducted with GLP certification, the test material (EC 231-272-0) was determined to have a glass transition point of - 60°C.
