Conclusions:
The decomposition of the test item was observed at 234.4 -235ºC under atmospheric pressure of 1001.2 hPa, below the boiling point.
Executive summary:

The determination of the boiling point of the test item was carried out according to OECD 103 and EU method A.2 (method according to Siwoloboff), following GLP. The capillary tube method was used with the BÜCHI Melting Point B-565 apparatus. The measurements were performed in three samples of the test item. The decomposition of the test item was observed at 234.4 -235ºC under atmospheric pressure of 1001.2 hPa, below the boiling point.

Description of key information

Key study: OECD 103 and EU method a.2. GLP study. The test item decomposes at 234.4 -235ºC under atmospheric pressure of 1001.2 hPa, below the boiling point.

Key value for chemical safety assessment
