Administrative data

Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Remarks:
The appearance of the test item is described in a reliable study report on the physical-chemical properties of the substance. Since no guideline was followed and no details on the methods are given, the description is considered as reliable with restrictions.
Cross-reference
Reason / purpose:
reference to same study
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
18 Jan 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
July 27, 1995
Deviations:
no
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Melting / freezing pt.:
>= -42 - <= -20.7 °C
Decomposition:
no
Remarks on result:
other: Pressure was not reported. It is assumed that melting point was tested at ambient conditions.

The peak corresponding to the melting of test item components was observed as a broad peak on the DSC chart. The range between the temperatures at the start and the end points of the peak was regarded as the melting range of test item. The measurement results are shown as follows:

Number of repetition

-42.0 to -20.7

2

Yellowish-brown liquid paste

-42.15 to -20.62

 

No adverse effects on the reliability of this test were noted.
