Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 27-12-2016 to 28-12-2016
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
OECD guideline study, test substance adequately identified. Reliability applies with restrictions, as not GLP and lack of experimental details.
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Qualifier:
according to guideline
Guideline:
other: ASTM E 537-86
GLP compliance:
no
Type of method:
thermal analysis
Remarks:
DSC
Specific details on test material used for the study:
- Storage condition of test material: between 15 and 35ºC, light protected
Key result
Melting / freezing pt.:
< -20 °C
Executive summary:

The freezing point of the test substance was determined according to OECD guideline, DSC method, with duplicate measurements. The onset temperature of -20°C was retained.

Description of key information

Freezing (i.e. solid-liquid transition) occurs at the temperature of -20°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

A reliable experimental study, conducted according to OECD guideline, DSC method, is available. Despite acceptable restrictions, it is considered as a key study. The result is retained as key data.
