Conclusions:
The decomposition of the test item was observed at a temperature of 258.6 ± 0.2 °C, below the boiling point.
Executive summary:

Determination of the boiling point of the test item was carried out according to EU method A.2 (method according to Siwoloboff) / OECD 103 (GLP study). A capillary containing the test item was heated in a boiling point apparatus in the range of 100 -400ºC, at atmospheric pressure of 1011 hPa. Under test conditions, all samples decomposed, turning dark brown, so the determination could only be done visually. The decomposition of the test item was observed at a temperature of 258.6 ± 0.2 °C, below the boiling point.

Description of key information

Key study. Method according to OECD 103 / EU method A.2, GLP study. The test item decomposes at 258.6 ± 0.2 °C (at 1011 hPa), below the boiling point.

Key value for chemical safety assessment
