Type of information:
experimental study
Adequacy of study:
key study
Study period:
07/15/2021 - 07/30/2021
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
according to guideline
EU Method A.2 (Boiling Temperature)
Version / remarks:
Council Regulation (EC) No 440/2008 of 30 May 2008
according to guideline
OECD Guideline 103 (Boiling Point)
GLP compliance:
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
276 °C
Atm. press.:
1 013 hPa
Decomp. temp.:
276 °C
Remarks on result:
other: The substance undergoes boiling with decomposition

No normal boiling point was found.

A partial boiling of the main compound starts at around 276 °C, probably already associated with decomposition.

The substance was found to undergo boiling with decomposition at 276°C using an appropriate guideline method not according to GLP. This result is considered reliable.

Description of key information

Boiling point/decomposition temperature: 276°C at 1013 hPa (OCED 103)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
276 °C
Temperature of decomposition (state purity):
276 °C

Additional information

The substance was found to undergo boiling with decomposition at 276°C using a differential scanning calorimetry method according to OECD Test Guideline 103. This result is considered reliable and is selected as key.


A predicted boiling point of 300°C at 1013 hPa was determined for the substance using an accepted QSAR estimation method. The result is considered to be reliable and is selected as key study.


In a secondary source to which no reliability could be assigned, a boiling point of 96°C at a very low pressure of 0.1 mmHg (13 Pa) was reported for the substance.
