Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
04 September 2018 - 05 November 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Qualifier:
equivalent or similar to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
yes (incl. certificate)
Type of method:
differential scanning calorimetry
Melting / freezing pt.:
>= 190 °C
Atm. press.:
> 101 - < 102.1 kPa
Decomposition:
yes
Decomp. temp.:
>= 190 °C
Remarks on result:
other: As the test item decomposed, no values for melting/freezing point and boiling point could be determined
Conclusions:
Decomposed from approximately 190 °C (493 K), at 101.0 to 102.1 kPa. As the test item decomposed, no values for melting/freezing point and boiling point could be determined.
Executive summary:

Test item decomposed from approximately 190 °C (493 K), at 101.0 to 102.1 kPa, by differential scanning calorimetry and using a modified liquid bath method, designed to be compatible with Methods A.1 Melting/Freezing Temperature and A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Methods 102 and 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no values for melting/freezing point and boiling point could be determined.

Description of key information
