Administrative data

Endpoint:
flash point of flammable liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
Cross-referenceopen allclose all
Reason / purpose for cross-reference:
data waiving: supporting information
Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From October 27, 2017 to February 27, 2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Appearance based on observations from other testing endpoints conducted on this substance
Reason / purpose for cross-reference:
reference to other study
Principles of method if other than guideline:
Observations basd on the observations made during testing for other endpoints.
GLP compliance:
yes
Physical state at 20°C and 1013 hPa:
solid
Remarks:
brown sticky
Key result
Form:
solid
Colour:
brown
Substance type:
organic
Conclusions:
The test substance is a brown sticky solid.
Executive summary:

The physical state and appearance of the test substance were visually observed during testing of other endpoints. The purified form of the test substance was identidied to be a brown sticky solid (Chilworth, 2018).

Reason / purpose for cross-reference:
data waiving: supporting information

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From October 27, 2017 to February 27, 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
not specified
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
not specified
GLP compliance:
yes
Type of method:
capillary method
Key result
Decomposition:
yes
Decomp. temp.:
ca. 89.7 °C
Remarks on result:
not determinable

Results:

Suspected decomposition was observed from 89.7°C with the release of colourless gas and the test sample moving up the tube. At 160°C the sample was observed to pop out of the tube with more sample ejected at 184°C. As a result further testing was stopped.

Conclusions:
Under the study conditions, melting point of the test substance could not be determined due to decomposition at 89.7°C.
Executive summary:

A study was conducted to determine the melting point of the test substance, using the capillary method (with photocell detection), according to OECD Guideline 102 and EU Method A.1, in compliance with GLP. During the study, suspected decomposition was observed from 89.7°C with the release of colourless gas and the test sample moving up the tube. At 160°C the sample was observed to pop out of the tube with more sample ejected at 184°C. As a result further testing was stopped. Under the study conditions, melting point of the test substance could not be determined due to decomposition at 89.7°C (Chilworth, 2018).
