- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- not specified
- GLP compliance:

- Type of method:
- method according to Siwoloboff
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 118 °C
- Conclusions:

- Executive summary:
A study was conducted to determine the boiling point of the test substance using Siwoloboff method, according to OECD Guidleine 103 and EU Method A.3, in compliance with GLP. During the study, suspected decomposition was observed from 118°C (melting was incomplete, violent bubbling, sample moving up the tube, and evolution of gas). At 128°C sample reacted violently with ejection of the boiling capillary from the tube. As a result the test was stopped. Under the study conditions, the boiling point of the test substance could not be determined due to decomposition (Chilworth, 2017).

Description of key information
Boiling point of the test substance was determined using the Siwoloboff method, according to OECD Guideline 103 and EU Method A.2 (Chilworth, 2017).
Key value for chemical safety assessment
Additional information
Value used for CSA: no boiling point determined due to decomposion at 118°C
