Description of key information

Weight of evidence: State of the substance at 20 °C and 101.3 kPa: clear colourless to clear liquid at temperatures > -20 °C, 2018

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid

Additional information

The weight of evidence is that the test item a clear colourless to clear liquid at temperatures > -20 °C. The test item has not been observed or is not expected to be a solid at > -20 °C.

 

The test item has been described as a clear colourless liquid and a clear liquid under standard conditions of temperature and pressure. The test item has a measured melting/freezing point of -41.3 °C under atmospheric pressure and boiling point of 289 ± 1°C at 98.0 kPa in an available melting point and boiling testing to EU Method A.1 and EU Method A.2 under GLP.

 

The test item under the CLP Regulation (EC) 1272/2008: Annex 1, section 1 concerning the definition of gases, liquids and solids, does not meet the criteria as a gas or solid. Therefore should be considered as a liquid.
